DEVICE OF INTERFERENCE COMPENSATION Russian patent published in 2009 - IPC G01S7/36 

FIELD: radiolocation.

SUBSTANCE: invention relates to radiolocation, can be used in targets detection equipment against the background of active interferences. Technical result is achieved ensured by that into mentioned device of active interference compensation, there are additionally introduced concatenated delay circuit, the second correlator, the first envelope demodulator, threshold device and key, the second input of which is connected to outlet of multiplicator, and outlet - to the second inlet of summator, input of delay circuit is connected to output of the main aerial, and the second input of the second correlator - to the output of compensatory aerial, and also concatenated the third correlator and the second envelope demodulator, output of which is connected to the second input of threshold device, the first input of the third correlator is connected to output of main aerial, and the second input - to the output of compensatory aerial, herewith delay period in delay circuit is selected on the assumption of providing interferences decorrelation of accepted main and compensatory aerials such as τ₃ > 1/"П", where "П" - bandwidth of reception path.

EFFECT: excluding of accumulation of inner noise of compensatory channel of active interferences interferences compensator during the absence on its inputs intercorrelated interferences.
