INTERFERENCE SUPPRESSOR Russian patent published in 2018 - IPC H03H7/12 G01S7/36 

FIELD: physics.

SUBSTANCE: invention is designed to isolate signals of moving targets against the background of passive interference during the group rearrangement of the carrier frequency of the probing pulses. Interference suppressor includes the first and the second delay units, a weighting coefficient unit, the first and the second complex multipliers, a weight block, a complex adder, a complex conjugation unit, a switching unit, an accuracy unit, a wiring unit and a two-channel switch interconnected in a certain way and carrying out a coherent processing of the original samples. The signal from the moving target and passive interference, significantly exceeding the useful signal in the quadrature phase detectors, is transferred to the video frequency and converted in such a way that the interference residues are compensated.

EFFECT: increasing the signal extraction efficiency of moving targets.
