SIGNAL DETECTOR Russian patent published in 2001 - IPC

FIELD: radiolocation, processing of signals in radars. SUBSTANCE: invention deals with exclusion of false detection of object caused by action of side lobes of compressed signal with preservation of parameters of consistent processing. It is also meant for design of device of weight filtration with capability of timely change of weight function of two-channel weight filter. This problem is solved thanks to use of different dependencies of level of legitimate signal and of levels of its side lobes on change of weight function. Signal detector has unit of weight filtration, threshold cell and prohibition cell. Unit of weight filtration incorporates multichannel subunit of weight filtration and detector of side lobe. Multichannel subunit of weight filtration has two-channel weight filter and weight summing device. EFFECT: exclusion of false detection of object. 7 cl, 10 dwg
