ADAPTIVE ANTENNA SYSTEM Russian patent published in 1997 - IPC

FIELD: radio and communication engineering. SUBSTANCE: adaptive antenna system has two antennas 1, two band filters 2, first and second adaptive compensators 3 and 4, respectively, first, second, third, an fourth weight multipliers 5,6,7, and 8, respectively adder 9, subtracter 10, and control unit 11. Signals picked off outputs of adder 9 and subtracter 10 go, respectively, to device outputs and further to receiver input through switching device. Introduced in addition are two adaptive compensators, subtracter, and control unit which enable obtaining signal-to-noise ratios across system outputs differently dependent on spatial position of signals (noise) thereby making it possible to split signals. EFFECT: improved noise immunity in receiving signals from moving objects when using double-antenna array independent of input signal power. 2 cl, 4 dwg
