METHOD FOR NOISE SUPPRESSION USING THREE-DIMENSIONAL SELECTION OF SIGNALS Russian patent published in 1997 - IPC

Abstract RU 2081514 C1

FIELD: radio engineering, in particular, adaptive antenna arrays. SUBSTANCE: method involves reception of mix of signal and M noises using N antenna elements which are divided into ν groups each of which has No antenna elements, where No= M+1. Then signals from ν are added. In particular, for each group method involves regulation of amplitude and phase of mix of signal and noise from each antenna element to required level so that signals are added in phase and noise voltage is neutralized. For first group required amplitude level is equal to corresponding amplitude level in first group; phase level is equal to sum of required phase in first group and phase levels corresponding of signal difference range. EFFECT: decreased number of calculations, simplified control of beam pattern, suppression of given number of interacting noises. 4 dwg
