DIGITAL NOISE SUPPRESSOR Russian patent published in 2002 - IPC

FIELD: radio engineering. SUBSTANCE: digital noise suppressor has main antenna( signal across antenna output presents sum of radar signal received by major lobe and noise signal received by minor lobes ) and three auxiliary antennas. Each of auxiliary antennas has directive gain determined by level of minor lobes of radiation pattern of main antenna. In this case antennas are displaced one relative another along base of antenna. Second subtracter which other input receives signal from output of auxiliary antenna and first subtracter which other input receives signal obtained as result of subtraction of signals of first and second auxiliary antennas transmitted through second multiplier are connected in series to output of main antenna. Signal generated as result of processing of signals from outputs of second and third auxiliary antennas goes to another input of second multiplier. EFFECT: enhanced operational efficiency due to decreased influence of components of radar signal on formation of weight coefficient. 2 dwg
