ADAPTIVE ANTENNA ARRAY Russian patent published in 1997 - IPC

FIELD: radio engineering and communications; radar and radionavigation systems, radio communication systems operating in noisy environment. SUBSTANCE: adaptive antenna array that has N antennas connected through complex weight multipliers to respective inputs of common adder, N adaptive circuits with control inputs whose first inputs are connected to outputs of respective antennas and second inputs, to output of common adder, and first outputs are connected to respective control inputs of complex weight amplifiers, is provided, in addition, with output power maximizing unit whose first and second inputs are connected, respectively, to first and second outputs of adaptive circuits and their outputs are connected to respective third inputs of adaptive circuits. EFFECT: improved noise immunity in receiving signals interrupted in the course of their transmission, such as pseudorandom working-frequency retuning signals. 2 cl, 12 dwg
