## 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.

3.6.1 Synchronize (with data word)
This Mode Code is sent by the Avionic System to the Radar to command the synchronization of the time tags of the Radar and of the different components of the Avionic System. The MC generates the Synchronize with data word at an approximate rate of 0.24 Hz. The format of the Data word is reported here below.

## 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.

## 5. ## 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.
Page 26
Cod. Rev. Data/Date Pag./Page
DECD_FTH A, draft 2 24/03/2015 26 di/of 413
− If the value of the time tag, provided by the MC in word 02 of message A4, does not change 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 ## COORDINATE FRAME DEFINITION
6.2.1 Earth-Centred Earth-Fixed Frame (E-Frame: X E , Y E , Z E )
| The origin is located at the mass centre of the Earth. | | | | | | | | | --- | | | | | | | | | X | E is directed North, along the polar axis. Y | | E and Z | E are in the equatorial plane, with Z | | | E directed | | through the Greenwich meridian, and Y | | E directed through 90 degree W longitude. | | | | | | | Geographic position, denoted in terms of geodetic latitude ( | | | | | φ ) longitude ( | λ ) and altitude (h) is | | | defined with respect to the earth-centred earth-fixed system as shown in Fig. 6.2,1. | | | | | | | | | |
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 | | | | | | | --- | | | | | | | instrument cluster from which the INU manufacturer computes accelerations, velocities and | | | | | | | translations. | | | | | | | X | G and Y | G are in a plane parallel to a plane that is tangent to the reference ellipsoid at the | | | | | geographic location of the INU, with X | | | | G pointed toward the True North and Y | G pointed toward the | | True West.

The angle from | | X | G to X is defined as Wander Angle (alpha) and depends on the INU characteristics. The sign | | | | | | | | convention of the Wander Angle is defined in Fig. 6.2,2 and in Fig. 6.2,4 | | | | | | | | | The polar system associated to the Navigation Frame, in accordance with the rule exposed in para | | | | | | | | | 6.1 will be referred to as NP-Frame: R, | | | | ψ , | θ . | | | | |
6.2.4 Rotated Navigation Frame (RN-Frame: X R , Y R , Z R )
| The origin is the same as that of X, Y, Z (Navigation) and X | | | | | | | | G , Y | G , Z | G (Local Geodetic) Frames. | | | | | | --- | | | | | | | | --- | --- | --- | | | | | | With reference to the Navigation frame, the Z | | | | R -axis is aligned with Z, X | | | | | | | R and Y | | R axes are in the | | | same plane as X and Y. The angle from X | | | R to X is the Platform Azimuth defined in Fig. 6.2,2 and | | | | | | | | | | | | | in Fig. 6.2,4. | | | | | | | | | | | | | | | | With reference to the Local Geodetic frame, the Z | | | | | R -axis is aligned with Z | | | | | | G ; X | R and Y | | R axes are in | | the same plane as X | G and Y | G . The angle from X | | R | to X | | G is the True Heading defined in Fig. 6.2,2 | | | | | | | | | and in Fig. 6.2,4. | | | | | | | | | | | | | | | | The polar system associated to the Rotated Navigation Frame, in accordance with the rule exposed | | | | | | | | | | | | | | | | in para 6.1 will be referred to as RNP-Frame: R | | | | R , ψ | R , | θ R | . | | | | | | | | | |
6.2.5 Aircraft Body Frame (B-Frame: X B , Y B , Z B )
| The origin is the same as that of X, Y, Z (Navigation) and X | | | | | | G , Y | G , Z | G (Local Geodetic) Frames. | | | | | --- | | | | | | --- | --- | --- | | | | | X | B is positive out the nose and it is coincident with the A/C centre line or aircraft roll axis, Y | | | | | | | | | | B is | | positive out the right wing (looking toward the positive direction of X | | | | | | | | | B ) and Z | B direction is such to | | | make the X | | B , Y | B , Z | B system right-hand (Z | B is out the belly of the aircraft), as shown in Fig. 6.2,2. | | | | | | |

DECD_FTH A, draft 2 24/03/2015 30 di/of 413
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).

6.2.9 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 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.

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).
