PASSIVE INTERFERENCE REJECTION FILTER Russian patent published in 2022 - IPC G01S7/36 

FIELD: radio location.

SUBSTANCE: invention relates to radio location equipment and is intended for isolating signals of moving targets against the background of passive interference with unknown correlation properties. In the passive interference rejection filter, estimates of the interference parameters are calculated, used in weighing of the counts thereof corresponding to the average element of the training sample, reducing the misalignment between the estimates obtained by averaging the counts of the training sample and the actual properties of the interference. The exclusion of the median element from the training sample allows for elimination of the possible influence of the signal on the interference compensation efficiency.

EFFECT: increase in the efficiency of isolation of signals of moving targets against the background of passive interference with a priori unknown correlation properties.
