SYSTEM FOR PROTECTING A RADAR STATION AGAINST INTERFERENCES

摘要

The proposed system for protecting a radar station against interferences contains a main receiver and an additional receiver of radar signals, a moving-target indicator, a unit for compensating interferences, and additionally, for the purpose to enhance the efficiency of suppression of passive and active interferences, two rejection filters, four low-pass filters, two differential amplifiers, two computing units, an adder, a reference signal source, and two valve elements. The unit for compensating interferences contains a phase changer, two balanced amplifiers, a subtracting unit, and a correlator in the feedback circuit. The corerlator contains a phase changer, two multipliers, and four low-pass filters.
