DEVICE FOR RADAR IDENTIFICATION OF TARGETS AGAINST THE BACKGROUND OF JAMMING Russian patent published in 1999 - IPC

FIELD: radio detection and ranging, applicable for detection and identification of artificial air targets at the background of passive jamming. SUBSTANCE: the device comprises the 4-th mixer, delay line, subtraction circuit, two integrators, full-wave rectifier, divider, identification unit and the 2-nd indicator with the respective variation of interunit couplings. Normalized sum of variations of the reflection intensity from pulse to pulse is the symptom of identification, and normalization is attained by division of the absolute sum of variations of reflections from the target by the weight factor, whose value is proportional to the target range, which is realized in the given device. EFFECT: identification of targets with non-linear characteristics in the conditions of jamming at the main sounding frequency. 1 dwg
