ADAPTIVE REJECTER FILTER OF PARALLEL STRUCTURE Russian patent published in 2006 - IPC G01S7/36 H03H21/00 

FIELD: radio engineering, possible use in coherent-impulse radio location stations for detecting and controlling aerial traffic for selecting signals from moving targets on background of passive interference of unknown correlation properties.

SUBSTANCE: rejection of passive interference by means of a parallel rejecter filter is based on m-channeled (with m=4) decomposition of vector H of rejecter filter of n-numbered order (with n=7) with integer-valued weight coefficients on channel vectors H₁,H₂,...,H_m, to projections of which h_i(m) integer-value condition is applied. To achieve aforementioned result, in conjunction with first channel, including seven memory blocks and first weight adder, additional channels are utilized, wherein accumulated rejection remainders are processed.

EFFECT: increased efficiency of rejection of passive interferences.
