DEVICE FOR SEMI-ACTUAL SIMULATION OF AIRCRAFT CONTROL SYSTEM WITH ACTIVE HOMING HEADS Russian patent published in 2019 - IPC F41G3/32 

FIELD: aviation.

SUBSTANCE: invention relates to devices for semi-real-time simulation of control system (CS) with homing heads (HH) of air and space aircrafts (SA), performance of tests and studies of operability and controllability of homing heads, as well as for debugging of program-algorithmic support of on-board digital computers (PC), which are part of CS and SA HH. Device comprises a flat active phased antenna array - APAA (14), which is a set of emitting elements (1), (2), (3), (6), (12), having a square or triangular shape on the plane of array (14), from which segments are formed, which imitates reflected signals from target (15), signals of noise interference (16) and signals of relay interference (18). Emissions of each of segments (15), (16), (18) are always directed towards the active self-guidance homing head - ASGHH (7), which together with the inertial control system (8) is installed on the dynamic rotary bench (5), which input is connected to the first output of computational-simulating unit (4), to the input of which signals from the inertial control system (8) are received. Second, third and fifth outputs of computing-simulating unit (4) are connected to second input of target simulation unit (9), to input of noise interference simulation unit (10) and with second input of relaying interference simulation unit (21), from which outputs signals are transmitted to first, second and third inputs of switching unit of radiating elements (13), output of which is connected to radiating elements (1), (2), (3), (6), (12). Fourth and sixth outputs of computing-simulating unit (4) are connected to fourth input of switching element of radiating elements (13) and to second input of signal receiving and processing unit (20), first input of which is connected to ASGHH (7) output, and the output is connected to the relay imitation unit (21) second input and to the target simulation unit (9) second input. Device comprises a signal receiving and processing unit (20), an input signal power meter unit, an attenuator unit, as well as a unit for simulating relay interference (21) with a unit for receiving pulse or continuous signals, a unit for modulating signals by amplitude, phase, frequency, a signal delay unit, a radiation control unit, a relay transmitting signal transmitting unit. First input of signal reception and processing unit is connected to ASGHH (7) output, second input is connected to sixth output of computation-modeling unit (4), output is connected to the first input of the target simulation unit (9) and to the first input of the relaying interference simulating unit (21). First input of the relaying interference simulation unit (21) is connected to the output of the signal receiving and processing unit (20). Second input is connected to fifth output of computation-simulating unit (4). Output is connected to the third input of the switching element of radiating elements (13).

EFFECT: possibility of performing works on debugging, testing, research, semi-real-time simulation of control and homing systems of space aircraft with AIGS, and also to imitate relay interference.
