DEVICE FOR ADAPTIVE PROCESSING OF ANTENNA ARRAY Russian patent published in 1998 - IPC

FIELD: hydroacoustics, in particular, equipment for shaping of beam pattern of antenna array using alternation of received oscillations. SUBSTANCE: device has N antennas, unit for shaping of phase distribution, unit for shaping beam pattern characteristics of working and compensation three-dimensional channels and adaptive noise compensating circuit. Gains of weight units of unit for shaping beam pattern characteristics of working channel Arn

for n= 1, N, where Arn - is gain of nth weight unit of unit for shaping beam pattern characteristics of this channel. Gains of weight units of unit for shaping beam pattern characteristics of compensation channel are , where Akn is gain of nth weight unit of unit for shaping beam pattern characteristics of compensation channel. EFFECT: increased efficiency of suppression of distributed noise which is present at same time outside of main antenna direction. 6 dwg
