METHOD FOR INCREASING THE RADAR RESOLVING POWER IN RANGE AND AZIMUTH

摘要

FIELD: radiolocation.;SUBSTANCE: the method consists in formation of the radar image matrix in the condition of a real ray with electronic scanning and with a successive shift of the radar ray in azimuth by the value of the n-th part of the aerial directional pattern width that is equal to the element of the increase of the resolving to the element of the increase of the resolving power in azimuth, and with successive shift of the range gates by the m-th part that is equal to the element of the increase of the resolving power in range, then using the obtained data, processing is performed separately for azimuth and separately for range according to the similar algorithm differing only in the weight coefficients, according to the readings of the signal numbered in the order of the shift of the positions of the aerial directional pattern (ADP), Fourier transform is fulfilled and the subsequent reverse transform with finding of a higher resolution of the separated object.;EFFECT: enhanced radar resolving power in range and azimuth (narrowing of the aerial directional pattern - ADP) with a simultaneous expansion of the radar scanned area).;6 dwg
