HARDWARE-OFF-LOOP SIMULATION METHOD OF AIRCRAFT HOMING SYSTEM AND DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: aviation.;SUBSTANCE: invention relates to the simulation of control systems (CS) with homing heads(HH) of air and space craft (A&SC). The active phased antenna array (APAA) is used, the segment of which is formed from the radiating elements APAA, and having a size of nm× elements, moves along the plane of the grid surface, thereby reproducing the relative movement of the aircraft and the target, and emits the desired signal, simulating the signal reflected from the target. At that, the phase surface of the APAA segment is oriented so, that the perpendicular to the phase surface of the APAA segment, along which the emission of the desired signal is formed, directed always to the homing head (HH), mounted on a dynamic rotary stand, and, moreover, it allows to generate additional segments, emitting signals, also always directed to the HH and imitating the radio noise environment for the HH, which is close to the real in almost the entire range of angular movement of the antenna HH A&SC.;EFFECT: expansion of passband and minimizing the amplitude-phase distortions.;2 cl, 3 dwg
