METHOD OF GENERATING RECEIVED SPATIAL-TIME SIGNAL REFLECTED FROM OBSERVED MULTIPOINT TARGET DURING OPERATION OF RADAR SYSTEM, AND BENCH SIMULATING TEST SPACE-TIME SIGNALS REFLECTED FROM OBSERVED MULTIPOINT TARGET, FOR TESTING SAMPLE OF RADAR SYSTEM Russian patent published in 2020 - IPC G01S13/78 G01S13/89 G01S7/40 

FIELD: radar ranging.

SUBSTANCE: group of inventions relates to radar ranging, in particular, to radar (r/l) means of measuring parameters of relative motion of spacecraft (SC). Method involves forming a matrix model of a space-time signal reflected from structural elements with unknown r/l reflection characteristics. Such a signal can be presented in the form of a matrix of complex numbers, each line of which represents a signal reflected from one point of the reflecting surface, so that evaluation of amplitudes of signals from all elements of the observed area form a r/l image of the obtained relief. Test bench simulating test signals for development of a sample of a radar system comprises a computing device which generates matrices whose rows represent numerical complex vectors which imitate both a useful signal, and all interfering signals, folded as readings of complex numbers on all columns of the matrix, and representing the obtained sums in the form of a quadrature digital sequence.

EFFECT: high measurement accuracy in conditions of re-reflection interference and reduced failure rate of operation of measurement systems of parameters of relative motion of spacecraft.
