RADAR SET Russian patent published in 1997 - IPC

FIELD: radar engineering; applicable in radar sets if independent and command control stations intended for detection of signals from targets and measurement of their coordinates at an existence of natural interference and jamming. SUBSTANCE: the radar set carries out the check of existence of spot jamming at the carrier frequency in the given repetition period, detection of one or several frequencies free of spot jamming in the process of frequency returning from period to period, operation at one of these frequencies in the coherent condition with Doppler frequency resolution, measurement of the spectrum width of interperiod fluctuations of the complex amplitude of reflected signals, and selection of signals from passive jamming of the shaft cloud type in the spectrum width of interperiod fluctuations. EFFECT: enhanced effectiveness. 7 cl, 10 dwg
