**## 3.**
            **## CHARACTERISTICS OF THE MIL-STD-1553 BUS INTERFACE**

**## 3.1**
            **## BUS OPERATION**

The Radar RT shall operate as a Remote Terminal in accordance with MIL-STD-1553B and Notice
2 thereto. Sole control of information transmission shall reside with the BUS Controller, which shall
initiate all transmissions.
In case of conflict, Requirements contained herein shall supersede those contained in MIL-STD-
1553B.


**## 3.2**
            **## INFORMATION TRANSFER MODES**

The Radar RT shall accept only the following modes of information transfer:
−
    Bus Controller (BC) to Remote Terminal (RT) transfer
−
    Remote Terminal (RT) to Bus Controller (BC) transfer
−
    Remote Terminal (RT) to Remote Terminal (RT) transfer
Broadcast commands are not allowed for data or information transfer. The Radar RT does not
produce any declaration of error or any malfunction whenever a broadcast command is received.



**## 3.3**
            **## DATA FORMATS**

Digital data shall be transmitted in a form compatible with the message and word formats defined in
section 7.
In establishing the message and word formats guidelines set in MIL-HDBK-1553 shall be followed,
as far as practicable.


**## 3.4**
            **## ADDRESS**

The Radar RT address shall be hardwired at the connector 4J3 of the Processor LRU.
Before setting the discrete signal FCR RT READY (whose characteristics are described in Selex ES
(SES) Document EICD_FTH) to logic “1”, the Radar shall determine its address (by reading the
connector hardwire programming).
Upon reception of each command word, the Radar shall compare the hard-wired address with the
address contained in the command word.
In the case the command word contains an invalid Radar RT address or in the case the parity check
is not successful, the Radar shall ignore such command word.
The address parity information shall be hardwired in the Processor connector 4J3.


**## 3.5**
            **## SUBADDRESS/MODE**

The subaddress field in the command word indicates the message to be transmitted or to be received
by the Radar. The subaddress values of 00000 and 11111 are reserved for special purpose (i.e. to
indicate the presence of a mode code) and shall not be utilized for any other function.

**## 3.7**
            **## STATUS WORD**

The following bits:
−
    Message Error Bit
−
    Busy Bit
−
    Subsystem Flag Bit
−
    Terminal Flag Bit
shall be implemented as specified in para 4.3.3.5.3.3; 4.3.3.5.3.8; 4.3.3.5.3.9 and 4.3.3.5.3.11 of
MIL-STD-1553B.

The following bits:
−
    Instrumentation
−
    Service Request Bit
−
    Reserved Status Bit
−
    Broadcast Command Received Bit
−
    Dynamic Bus Control Acceptance Bit
shall not be implemented and shall be set to logic “0”.


**3.7.1**
            **Message Error Bit Management**

This bit is managed in accordance with MIL-STD-1553B (Notice 2) to indicate illegal or invalid
command detection.
A command is considered illegal when it contains a subaddress and/or word count different from
those listed in 3.5 or a mode code different from those listed in 3.6.


**3.7.2**
            **Busy Bit Management**

Any busy condition in the Radar RT that would affect communication over the bus shall be
conveyed via the busy bit. Busy conditions, and thus the setting of the busy bit, shall occur only as a
result of particular commands/messages sent to the Radar RT.
The Busy Bit will not be set as a result of failure within the Radar RT. In such a case the Terminal
Flag Bit and/or the Subsystem Flag Bit will be set accordingly.


**3.7.3**
            **Subsystem Flag Bit Management**

This bit is set to logic “1” whenever the Main Control Processor of the Radar Main Computer is in a
failure condition, and is unable to communicate on 1553 bus.


**3.7.4**
            **Terminal Flag Bit Management**

This bit is set to logic “1” whenever the Radar RT interface circuitry is in a failure condition.


**3.7.5**
            **Status Word Parity**

Odd parity shall be used for status word.

**## 3.8**
            **## COUPLING ON THE BUS**

Transformer coupling as defined in paragraph 4.5.1.5.1 of MIL-STD-1553B shall be used.



**## 3.9**
            **## TIME TAG**

a)
    Time Tag (transmit): Time information relevant to the data flowing from Radar to the Avionic
    System shall be implemented in the message format as specified in section 7. The timer shall
    be free running with an LSB of 64 µ sec. The time tag shall reflect the time at which the
    associated data are sampled.
b)
    Time Tag (receive): Data relevant to the aircraft altitude, attitude, attitude rates and
    acceleration, velocity and acceleration shall be transmitted to the Radar with time tag
    information.
This timer shall have a resolution of 64 µ sec. The Time Tag shall reflect the time at which the
associated data are sampled.


**3.9.1**
            **Time Tags Synchronization**

The timing origin shall be the same for both timers (Transmit and Receive) and shall be preset to
the value provided by the Synchronize with Data Word Mode command.



**## 3.10**
            **## DATA WRAPAROUND**

The Radar RT shall implement a data wraparound capability with subaddress 30 (11110). The
Radar RT shall be capable of receiving and transmitting 32 data words at this subaddress. A valid
Receive message with this subaddress to the Radar RT shall cause the Radar RT to store the
commanded number of data words.
A valid Transmit command with this subaddress to the Radar RT shall cause the Radar RT to
transmit the commanded number of stored data words. The data words shall be transmitted in the
same order as the words received by this subaddress. Any intervening valid receive command to the
Radar RT may alter the content of the stored data.
The stored data words are available for the transmission if the Transmit command occurs not before
80 msec after the reception of a valid Receive message.

The structure of the sequence of transmission of the messages listed in Tab. 3.11-1 and in Tab. 3.11-2
will be in accordance to the following rules:
1)
    The nominal transmission rate of each message will be in accordance with Tab. 3.11-1 and
    Tab. 3.11-2.
2)
    The radar can accept, without any malfunction, a reduction of the rate of transmission of the
    messages. However, the following limitations have to be considered:
    a)
            The rate of messages A2 and A4 should comply with the minimum rate required to
            prevent the declaration of back-up conditions, as described in section 5.
    b)
            A reduction in the rate of messages A2 and B7 should induce unacceptable effect in the
            Man Machine Interface, as far as the mode transition is concerned
    c)
            A reduction in the rate of message B1, B2, B3 and B4, B5 produces corresponding
            degradation in the quality and accuracy of the tracking data provided to the Avionics.
3)
    The average transmission rate will be such that no more than 10 messages are transmitted
    each 20 msec.
4)
    The messages A7 and A8, when present in the frame, will be always inserted consecutively.
5)
    The messages B1, B2 and B3 will be always inserted in the frame consecutively.
6)
    Message B1, B2 or B3 has not to be inserted in the frame within 80 ms from the transmission
    of the last B3 message.
7)
    The messages B4 and B5 will be always inserted in the frame consecutively.
8)
    The messages B9 and B10, when present in the frame, will be always inserted consecutively.

            **## RADAR OPERATION IN DEGRADED CONDITION**

The radar is designed to operate, with degraded performance and limited capability, when part of
the data received via 1553 bus from the Mission Computer (MC) and/or from the INU are absent or
invalid.
In any case, the radar is designed to avoid any uncontrolled behaviour and any damage in case of
failure of the MC. In particular the following provisions are taken:
−
    If the MC does not provide a valid message A2 (RDR Operational Command) for a time
    greater than 2 sec, the radar enters STBY (on RWS mode) whatever is the current status.

    for a time greater than 2 sec, the radar enters STBY (on RWS mode) whatever is the current
    status.

The detailed description of the back-up operation of the radar as a consequence of the absence of
data is in SES document LOO_FTH.

**## 6.**
            **## REFERENCE SYSTEMS**

This section describes the reference co-ordinate systems that are used both in the Radar and in the
Avionics to define the data transferred on the 1553 Bus between Radar and MC.


**## 6.1**
            **## CARTESIAN AND POLAR SYSTEMS**

All the cartesian coordinate systems used are orthogonal right hand.
This means that an observer with own feet on the X-Y plane and lying along the positive direction
of the Z-axis sees the rotation of X-axis toward the Y-axis through 90 ° to occur counter clockwise
(CCW).
Whenever a spherical polar coordinate system is associated to a XYZ Cartesian system, it will have
the same origin (O).

Let OP be the vector from the origin to the point of interest P.
The Azimuth Angle (AZ or ψ ) is the minimum angle between the positive direction of the X-axis
and the projection of the vector OP on the X-Y plane (OP’).
Such angle is positive if the rotation of the positive direction of the X-axis toward the projection
OP’ of OP through the minimum angle is seen to occur counter clockwise by the positive direction
of the Z-axis.
The Elevation Angle will be measured in a plane perpendicular to the X-Y plane containing both
the Z-axis and the point of interest (P). The Elevation angle is the angle in such plane between the
vector OP and the X-Y plane. The Elevation Angle (EL or θ ) is positive if the point of interest (P) is
in the same half space as the positive direction of the Z-axis.

The relationship between a XYZ Cartesian system and the associated polar spherical system is
shown in Fig. 6.1,1.

|  |


**6.2.2**
            **Local Geodetic Frame (G-Frame: X** **G** **, Y** **G** **, Z** **G** **)**


| The origin is located at the computed specific force origin of the INU. This point is the point in the |  |  |  |  |  |

The Euler angles of the Navigation Frame with respect to the Body Frame are:
•
    − platform azimuth
•
    pitch
•
    roll + π
The Euler angles of the Local Geodetic Frame with respect to the Body Frame are:
•
    − true heading
•
    pitch
•
    roll + π
The polar system associated to the Body frame, in accordance with the rule exposed in para 6.1, will
be referred to as BP-Frame: R B , ψ B , θ B .


**6.2.6**
            **Bulkhead Fuselage Station Frame (FS-Frame: X** **FS** **, Y** **FS** **, Z** **FS** **)**

The origin is the intersection of the X B axis of the Body Frame with the Fuselage Station where the
Bulkhead is installed.
The orientation of the axes is the same as that of the Body Frame.
This frame is obtained from the Body Frame with a translation, accounting for the displacement of
the Bulkhead plane with respect to the origin of the Body Frame, and a rotation, taking into account
the imperfect bulkhead installation and the dynamic deformation of the Aircraft fuselage during
flight. The parameters characterizing the transformation are described in section 6.2.11.


**6.2.7**
            **Antenna Frame (A-Frame: X** **A** **, Y** **A** **, Z** **A** **)**

The origin is the pivot point of the antenna gimbal as shown in Fig. 6.2,3.
The AZ pivot point and the EL pivot point of the antenna gimbal are coincident. The gimbal order
is (from the Flat Plate Array Antenna) Elevation over Azimuth.
The X A axis is perpendicular to the surface determined by the Pedestal mounting feet and is positive
from the array into the space. The Z A axis is the rotation axis of the Azimuth movement. The Z A
positive direction is that of an observer which sees the antenna scanning from the left to the right in
the counter clockwise direction. The Y A axis orientation is such to make the X A , Y A , Z A system
right-hand.
This frame is obtained from the Bulkhead Fuselage Station Frame with a rotation, which takes into
account the installation of the Antenna Assy on the bulkhead, and a translation, taking into account
the physical dimensions of the Antenna Assy, i.e. the displacement of the Antenna Pivot Point with
respect to the mounting surface of the Antenna Assy.
The Euler angles of the transformation are described in section 6.2.10; the translation is as derived
from Fig. 6.2,3.


**6.2.8**
            **Target polar system (T-Frame:** ψ **T** **,** θ **T** **, R** **T** **)**

The target polar system has the same origin as the A-frame.
The azimuth ( ψ T ) and elevation ( θ T ) angles are those measured by the azimuth and elevation
encoders of the Antenna Assy and their orientation are given by the rule which associates this polar
frame to the A-frame in accordance with section 6.1.
The Antenna Array and the Antenna Pedestal are manufactured and trimmed in factory in such a
way that the Target Polar System (T-Frame) is aligned with the Antenna Frame (A-Frame).

            **Definition of INU Azimuth angles**

The INU azimuth angles of interest in the XY plane of the Navigation Frame are defined in Fig.
6.2,4.


**6.2.10**
            **Antenna harmonization**


| The purpose of the antenna harmonization procedure is the measurement of the angular relationship |  |  |  |  |  |  |  |  |  |  |  |
| --- |  |  |  |  |  |  |  |  |  |  |  |
| between the Bulkhead Fuselage Station Frame and the Antenna Frame (X |  |  |  |  |  |  |  | A , Y | A , Z | A ) when the |  |
| Antenna Assy is mounted on the aircraft bulkhead. |  |  |  |  |  |  |  |  |  |  |  |
| This angular relationship is expressed through the three Euler angles ( |  |  |  |  |  | ψ | H (yaw), |  | θ | H (pitch), | ϕ H |
| (roll)) between the Antenna Frame and the Bulkhead Fuselage Station Frame. The sign convention |  |  |  |  |  |  |  |  |  |  |  |
| for the three angles is the same as for the platform azimuth, pitch and roll angles defined in section |  |  |  |  |  |  |  |  |  |  |  |
| 6.2.5 and shown in fig. 6.2,2. In particular, |  |  |  | ϕ H | (roll angle) is positive for a clockwise rotation of the |  |  |  |  |  |  |
| Y | A axis, as seen by the pilot; | θ H | (pitch angle) is positive up, with respect to the fuselage, and |  |  |  |  |  |  |  | ψ H |
| (yaw) is positive for a rotation toward the right wing. |  |  |  |  |  |  |  |  |  |  |  |
| The three Euler angles can be provided to the Radar via the words A1/09-10 (parameter transfer) of |  |  |  |  |  |  |  |  |  |  |  |
| the 1553 bus. |  |  |  |  |  |  |  |  |  |  |  |
|  |


**6.2.11**
            **Aircraft Flexure Data**

The displacement of the Bulkhead Fuselage Station Frame with respect to the Body Frame depends
on the aircraft structural characteristics and on the dynamic deformation of the Aircraft fuselage
during flight.
The relative displacement of the FS Frame with respect to the Body Frame is completely
determined by:
−
    Coordinates of the origin of the FS frame in the Body Frame (three parameters), which can be
    provided to the Radar via the words A1/09-10 (parameter transfer) of the 1553 bus.
−
    Euler angles of the FS frame with respect to the Body Frame (three parameters).

**NOTE 1:**
                Bit 00 indicates if the request for transmit/receive a parameter is active, as indicated
                in Tab. A1/08-A.

                Each transfer request commanded in this field has to be held for at least 2 cycles (200
                ms) and then reset to the value “NOT ACTIVE”. The Radar shall not serve any other
                request until this field is reset to “NOT ACTIVE” for at least 2 cycles (200 ms).



                                    Tab. A1/08-A - Field A Description

                Parameter Transfer

                Remark a)
                            If this field is set to “NOT ACTIVE”, no request of transmit/receive of
                            parameters is present. Consequently, the content of fields B and C of
                            this word and the content of words A1/09 and A1/10 are not significant

                Remark b)
                            If this field is set to “ACTIVE”, a request of transmit/receive of the
                            parameter indicated in field C is in progress.


**NOTE 2:**
                Bit 01 selects the operation to be done on the parameter, as indicated in Tab. A1/08-
                B.

Remark a)
                If this field is set to “RECEIVE”, the parameter identified in field C is
                available in words A1/09 and A1/10, and can be read by the Radar.

Remark b)
                If this field is set to “TRANSMIT”, the parameter identified in field C
                has to be provided in output by the Radar in message B9.

    Remark b)
                When received from MC, the value of this parameter is stored by the
                Radar in EEPROM, and used immediately.
    Remark c)
                When received from MC, the value of this parameter is used
                immediately. It is not stored in EEPROM, and consequently it is lost
                (and the default value resumed) at the next Radar Power-Off.
    Remark d)
                This parameter is defined in section 6.2.10.
    Remark e)
                This parameter is defined in section 6.2.11.
    Remark f)
                This parameter is defined in SES Document SA5169.
    Remark g)
                This parameter is reserved for experimental purposes.

**NOTE 1:**
            These two words contain the value of the parameter, identified by the value in field C of word
            A1/08, which has to be received by the Radar. These words are significant only when the field B
            of A1/08 is set to “RECEIVE”. The format for all the parameters, except those reserved for
            experimental purposes, is described in the following pages.

**Remarks:**

1)
    The fields composing this word are served by the Radar with the following priority order:
                    F - G - C - D - A - B - E - H
    If a transition is commanded in a field, another transition commanded in a field with lower priority is not served until
    the first transition is completed.

**NOTE 1:**
                Bit 00 through 03 compose a four bit binary coded word (MSB = Bit 00) defining the
                required Radar operating mode, as indicated in Tab. A2/01-A.

                The content of this field represents the Master Mode in which the Radar is
                commanded to operate.

                Whenever the field A of B7/01 is set to “DLY” or the field C of B7/01 is set to “INT-
                BIT In Progress”, this field is disregarded by the Radar.

**NOTE 3:**
                Bit 04 through 07 compose a three bit binary coded word defining the required
                designation command, as indicated in Tab. A2/01-B.
                The content of this field represents a request of transition among the status of the
                Master Mode currently performed by the Radar.
                Each selection commanded in this field has to be held for at least 2 cycles (80 ms)
                and then reset to the value “NOT VALID”. The Radar shall not serve any other
                transition neither in field A nor in field B until the field B is reset to “NOT VALID”
                for at least 2 cycles (80 ms).

                Whenever the field A of B7/01 is set to “DLY”, or the field C of B7/01 is set to
                “INT-BIT In Progress”, or the field D of B7/01 is set to “STBY ON”, this field is
                disregarded by the Radar.

                required number of elevation bars, as indicated in Tab. A2/02-G.

                This field is disregarded by the Radar when either the SPOT function is commanded
                (as indicated by field B of A2/02) or one of the following modes is selected: RWS or
                SAM (with ASM submode selected), TWS, ACM, GM, SEA-1, SEA-2, GMTI,
                AGR, TA, WA. This field is also disregarded if the radar is performing a Single
                Target Track mode (i.e. STT, FTT, SSTT, GMTT, SMTT).

                In these cases the number of bars is either not applicable or automatically selected by
                the Radar.

**NOTE 8:**
                Bit 12 and 13 compose a two bit binary coded word (MSB=BIT 12) defining the
                required azimuth scan width as indicated in Tab. A2/02-I.

                Azimuth scan width is defined as the azimuth angle scanned by the antenna Line-of-
                Sight (LOS) in the polar system associated to the X, Y, Z Navigation Frame.

                This field is disregarded by the Radar when:
                • The ASM submode of the RWS is selected (Field A of A2/01 set to “RWS” and
                field A of A2/02 set to “RWS ASM”);
                • The SPOT function is selected (field B of A2/02 set to “SPOT”);
                • ACM or AGR mode is selected (field A of A2/01 set to “ACM” or to “AGR”);
                • STT, FTT, SSTT or SMTT mode is being performed.

                If the Radar is operating in SAM (Field A of B7/01 set to “RWS” and field B of
                B7/01 set to “SAM”), the content of this field represents the desired azimuth scan
                width.

Remark a)
                This value of the azimuth scan width cannot be selected when TWS
                Master Mode is commanded (field A of A2/01 set to “TWS”).

Remark b)
                This value of the azimuth scan width can be selected only when TWS
                Master Mode is commanded (field A of A2/01 set to “TWS”).

Remark c)
                When either GMTI or SEA-2 mode is commanded (field A of A2/01 set
                to “GMTI” or to “SEA-2”), this value of the azimuth scan width
                corresponds to ±45 ° , otherwise to ±60 ° .

Remark d)
                When TA mode is commanded (field A of A2/01 set to “TA”), this
                value of the azimuth scan width cannot be selected.

**NOTE 1:**
                The content of this word is significant only if bit 00 of A3/01 is set to “1”.

**NOTE 2:**
                Bit 00 through bit 16 of MSW and Bit 00 through bit 08 of LSW compose a twenty-
                five bit word represented in 2’s complement format which defines the Latitude of the
                Waypoint 1 symbol. The units are Semicircles, the MAX value is 1.0, the MIN value
                is -1.0, the MSB is 0.5, the LSB is 5.96046 E-8 and the full scale is 1.0.

**NOTE 3:**
                Bit 09 of LSW controls the Waypoint/FYT selection, as indicated in Tab. A3/04-B.

**NOTE 1:**
                The content of this word is significant only if bit 01 of A3/01 is set to “1”.

**NOTE 2:**
                Bit 00 through bit 16 of MSW and Bit 00 through bit 08 of LSW compose a twenty-
                five bit word represented in 2’s complement format which defines the Latitude of the
                Waypoint 2 symbol. The units are Semicircles, the MAX value is 1.0, the MIN value
                is -1.0, the MSB is 0.5, the LSB is 5.96046 E-8 and the full scale is 1.0.

**NOTE 3:**
                Bit 09 of LSW controls the Waypoint/FYT selection, as indicated in Tab. A3/08-B.

**NOTE 1:**
                The content of this word is significant only if bit 02 of A3/01 is set to “1”.

**NOTE 2:**
                Bit 00 through bit 16 of MSW and Bit 00 through bit 08 of LSW compose a twenty-
                five bit word represented in 2’s complement format which defines the Latitude of the
                Waypoint 3 symbol. The units are Semicircles, the MAX value is 1.0, the MIN value
                is -1.0, the MSB is 0.5, the LSB is 5.96046 E-8 and the full scale is 1.0.

**NOTE 3:**
                Bit 09 of LSW controls the Waypoint/FYT selection, as indicated in Tab. A3/12-B.

**NOTE 1:**
                The content of this word is significant only if bit 03 of A3/01 is set to “1”.

**NOTE 2:**
                Bit 00 through bit 09 compose a nine bit binary coded word (MSB = Bit 00) which
                defines the X-Display coordinate of the Intercept Flight Director symbol. The units
                are Pixels, the MAX value is 573, the MIN value is 0, the MSB is 512, the LSB is 1
                and the full scale is 1023.

**NOTE 3:**
                Bit 10 controls the Intercept Mode selection, as indicated in Tab. A3/15-B.

**NOTE 1:**
                If this bit is set to “1”, the following Navigation data provided by the INU are not
                valid and have to be disregarded by the Radar:
                • X, Y, Z Velocity (words 03 ÷ 08 of A5);
                • X, Y, Z Acceleration (words 05 ÷ 07 of A4);
                • nx, ny, nz Acceleration (words 15 ÷ 17 of A5).

**NOTE 2:**
                If this bit is set to “1”, the following Attitude data provided by the INU are not valid
                and have to be disregarded by the Radar:
                • Present True Heading (word 03 of A4);
                • Present Magnetic Heading (word 04 of A4);
                • Platform Azimuth, Roll, Pitch (words 09 ÷ 11 of A5).
                • Roll rate, Pitch rate, Yaw rate (words 12 ÷ 14 of A5);
                • Roll, Pitch and Yaw Angular Accelerations (words 21 ÷ 23 of A5).

**NOTE 3:**
                If this bit is set to “1”, the content of word 10 of A4 (Inertial altitude provided by the
                INU, or Barometric altitude provided by the DADC) is not valid and has to be
                disregarded by the Radar.

**NOTE 4:**
                If this bit is set to “1”, the content of word 11 of A4 (Corrected Barometric altitude
                provided by the MC) is not valid and has to be disregarded by the Radar.

**NOTE 5:**
                If this bit is set to “1”, the Radio Altimeter Altitude data (word 12 of message A4) is
                not valid and has to be disregarded by the Radar.

**NOTE 6:**
                If this bit is set to “1”, the SPOI Altitude data (word 13 of message A4) is not valid
                and the Radar assumes the value ‘0’ as default.

**NOTE 7:**
                If this bit is set to “1”, the SPOI Position data (words 28 ÷ 31 of message A4) are not
                valid and have to be disregarded by the Radar.

**NOTE 8:**
                If this bit is set to “1”, the True Air Speed data provided by the DADC (word 08 of
                message A4) is not valid and has to be disregarded by the Radar.

**NOTE 9:**
                If this bit is set to “1”, the Calibrated Air Speed data (word 09 of message A4) is not
                valid and has to be disregarded by the Radar.

**NOTE 10:**
                If this bit is set to “1”, the Present Position data (time tag, latitude and longitude:
                words 23 ÷ 27 of message A4) are not valid and have to be disregarded by the Radar.

**NOTE 11:**
                If this bit is set to “1”, the EL Antenna Demand (word 18 of A4) is changing because
                of an action of the pilot (tilt up/down or “Antenna set” command).

**NOTE 12:**
                If this bit is set to “1”, the Cursor Rates data (field A of word 19 and field A of word
                20 of message A4) are not valid and have to be disregarded by the Radar.

**NOTE 13:**
                Bit 12 controls the selection between Normal and Slave options for the cursor
                management, as indicated in Tab. A4/01-M.

                This field is served by the Radar only when the Radar is operating in one of the
                following modes: RWS, SAM, TWS, VS, as shown in fields A and B of B7/01.

                Remark a)
                            If this field is set to “NORMAL”, the radar ignores the content of
                            words 21 and 22 of message A4.

                Remark b)
                            If this field is set to “SLAVE”, the radar ignores the content of field A
                            of word 19 and field A of word 20 of message A4.

**NOTE 14:**
                If this bit is set to “1”, the “Cursor Zero” command is active.

**NOTE 15:**
                Bit 14 controls the selection between Normal and Snowplough options for the cursor
                management in Air-to-Surface modes, as indicated in Tab. A4/01-O.

                This field is served by the Radar only when the Radar is operating in one of the
                following modes: GM, GMTI, SEA-1, SEA-2, as shown in fields A and B of B7/01,
                and in BCN, when one scan bar is performed (A/S submode), as shown in field A of
                B7/01 and in field G of B7/02. Moreover, this field is served provided that neither
                Expand nor Freeze functions are selected.

**NOTE 3:**
                Bit 02 through bit 04 compose a three bit binary coded word (MSB = Bit 02) which
                defines the Velocity of the DL Target 01/02/03/04/05. The units are knots, the MAX
                value is 1,000, the MIN value is 0, the MSB is 572, the LSB is 143 and the full scale
                is 1,001.
                If the DL target is a DL Member or a DL HPM (field A set to decimal value 02 or to
                decimal value 03) the content of this field is not significant.

**NOTE 4:**
                Bit 05 through bit 11 compose a seven bit binary coded word (MSB = Bit 05) which
                defines the Altitude of the DL Target 01/02/03/04/05. The units are kfeet, the MAX
                value is 99, the MIN value is 0, the MSB is 64, the LSB is 1 and the full scale is 127.

**NOTE 5:**
                If this bit is set to “1”, the relevant DL target is within the Intercept Zone.
                If the DL target is a DL Member or a DL HPM (field A set to decimal value 02 or to
                decimal value 03) the content of this field is not significant.

**NOTE 3:**
                Bit 02 through bit 04 compose a three bit binary coded word (MSB = Bit 02) which
                defines the Velocity of the DL Target 06/07/08/09/10. The units are knots, the MAX
                value is 1,000, the MIN value is 0, the MSB is 572, the LSB is 143 and the full scale
                is 1,001.
                If the DL target is a DL Member or a DL HPM (field A set to decimal value 02 or to
                decimal value 03) the content of this field is not significant.

**NOTE 4:**
                Bit 05 through bit 11 compose a seven bit binary coded word (MSB = Bit 05) which
                defines the Altitude of the DL Target 06/07/08/09/10. The units are kfeet, the MAX
                value is 99, the MIN value is 0, the MSB is 64, the LSB is 1 and the full scale is 127.

**NOTE 5:**
                If this bit is set to “1”, the relevant DL target is within the Intercept Zone.
                If the DL target is a DL Member or a DL HPM (field A set to decimal value 02 or to
                decimal value 03) the content of this field is not significant.

**NOTE 1:**
                This word represents the Normalized component of the tracked target position along
                the X axis of the XYZ Navigation frame. If the Radar is performing AOJ on the
                tracked target, it represents the director cosine of the tracked jammer direction along
                the same axis, multiplied by the fixed value 32,000.

**NOTE 2:**
                The value of the component can be obtained by multiplying the Normalized value
                contained in this word by an appropriate factor, which is obtained from the

**NOTE 1:**
            This word represents the estimated aspect angle of the tracked target (+180 ° is for head-on
            target). The sign of the aspect angle is positive clockwise. This corresponds (in condition of zero
            roll for both interceptor and target) to a value positive when the interceptor faces the right side of
            the target, and to a value negative when the interceptor faces the left side of the target.
**NOTE 2:**
            The content of this word is not significant if the Radar is performing AOJ on the tracked target.

**NOTE 12:**
                This field is significant only when the Radar is performing FTT. This field is set to 1
                when the Radar detects that the tracked target is moving.

**NOTE 13:**
                This field is set to 1 whenever a change of HPT is performed, either upon manual
                command by the pilot, or automatically by the radar. In particular, the field is set to 1
                when:
                -
                In TWS a new HPT is selected by the pilot (via Lock-On or Transfer of HPT
                bug)
                -
                In TWS a new HPT is selected by the radar (because of change of priority, or loss
                of the previous HPT)
                -
                In DTT the HPT bug is transferred to the SPT by the pilot (via Transfer of HPT
                Bug)
                -
                In DTT, the HPT is lost, and the SPT becomes the new HPT (and the SAM is
                entered)
                -
                In SAM, a new HPT is acquired via pilot designation
                The setting to 1 in this field has to be held for at least 2 cycles (40 ms) and then reset
                to the value 0. The Radar shall not serve any further transition in this field until the
                field is reset to 0 for at least 2 cycles (40 ms).

**NOTE 14:**
                This field is set to 1 whenever a rejection of SPT is performed, upon manual
                command by the pilot. In particular, the field is set to 1 when:
                -
                In TWS a SPT is selected by the pilot (via “Single PT Reject”)
                The setting to 1 in this field has to be held for at least 2 cycles (40 ms) and then reset
                to the value 0. The Radar shall not serve any further transition in this field until the
                field is reset to 0 for at least 2 cycles (40 ms).

**NOTE 1:**
                If the Radar operates in STT, SAM, DTT, TWS, SSTT, SMTT, GMTT, FTT, this
                word represents the Normalized component of the tracked target position along the Z
                axis of the XYZ Navigation frame. If the Radar is performing AOJ on the tracked
                target, it represents the director cosine of the tracked jammer direction along the
                same axis, multiplied by the fixed value 32,000.

**NOTE 2:**
                If the Radar operates in AGR, this word represents the estimated normalized height
                above ground.

**NOTE 3:**
                The value of the component can be obtained by multiplying the Normalized value
                contained in this word by an appropriate factor, which is obtained from the
                Normalization factor defined by field G of word B5/02, as indicated in the following

**NOTE 1:**
            This word represents (in SAM, A/A STT and TWS modes) the estimated aspect angle of the
            tracked target (+180 ° is for head-on target). The sign of the aspect angle is positive clockwise.
            This corresponds (in condition of zero roll for both interceptor and target) to a value positive when
            the interceptor faces the right side of the target, and to a value negative when the interceptor
            faces the left side of the target.
**NOTE 2:**
            This word represents (in SSTT, SMTT and GMTT modes) the estimated Ground Track Angle of
            the tracked target. It is referred to the Navigation Frame, and is positive counter-clockwise (i.e. it is
            0 degrees when the target moves along the x axis of the Navigation frame, and is 90 degrees
            when the target moves along the y axis of the Navigation Frame).
**NOTE 3:**
            The content of this word is not significant if the Radar is operating in AGR or FTT.
**NOTE 4:**
            The content of this word is not significant if the Radar is performing AOJ on the tracked target.

**NOTE 1:**
                The content of this word is significant only if the Radar is operating in TA.

**NOTE 2:**
                Bit 00 through bit 11 compose a twelve bit binary coded word (MSB = Bit 00) which
                defines the minimum range of protrusion through the high clearance plane within the
                central corridor, measured along the local horizontal plane (i.e. ground measured
                range).

**NOTE 3:**
                The range of protrusion has to be considered not valid when the content of field A
                assumes the value 0.

**NOTE 4:**
                Bit 12 indicates the absence of significant signal, as indicated in Tab. B6/11-B.

**NOTE 1:**
                The content of this word is significant only if the Radar is operating in TA.

**NOTE 2:**
                Bit 00 through bit 11 compose a twelve bit binary coded word (MSB = Bit 00) which
                defines the minimum range of protrusion through the low clearance plane within the
                central corridor, measured along the local horizontal plane (i.e. ground measured
                range).

**NOTE 3:**
                The range of protrusion has to be considered not valid when the content of field A
                assumes the value 0.

                Bit 00 indicates if the request for transmit/receive a parameter is active, as indicated
                in Tab. B6/13-A.

                                                    b)


Remark a)
                If this field is set to “NOT ACTIVE”, no action of transmit/receive of
                parameters is in progress. Consequently, the content of fields B, C and
                D of this word and the content of words B6/14 and B6/15 are not
                significant.

Remark b)
                If this field is set to “ACTIVE”, the Radar is managing the request of
                transmit/receive of the parameter indicated in field C.

                            If this field is set to “RECEIVED”, the parameter identified in field C
                            has been received from words A1/09 and A1/10, and is available, as
                            tell-back, in words B6/14 and B6/15.

                Remark b)
                            If this field is set to “TRANSMITTED”, the parameter identified in
                            field C has been made available by the Radar in words B6/14 and
                            B6/15.


**NOTE 3:**
                Bit 02 through bit 09 compose a eight bit binary coded word (MSB = Bit 02) which
                identifies the parameter which has been received/transmitted by the Radar.
                The parameters received/transmitted by the Radar are listed in Note 3 to word 08 of
                message A1.
