ROTARY FILTER Russian patent published in 2021 - IPC H03H7/12 G01S13/524 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and is intended to isolate signals from moving targets against the background of passive interference with unknown correlation properties. The specified result is achieved in that the notch filter contains a weighting unit, first and second complex adders, first, second, third and fourth delay units, a weighting coefficient calculator and a sync generator, connected in a certain way to each other and performing adaptive coherent processing of the original digital samples.

EFFECT: increasing the efficiency of detecting signals from moving targets against the background of passive interference with a priori unknown correlation properties.
