ADAPTIVE ANTENNA ARRAY Russian patent published in 1997 - IPC

FIELD: radio engineering, in particular, antenna devices which operate in jam conditions. SUBSTANCE: device has N serial circuits of emitters and mixers. Outputs of mixers are connected to adder. second inputs of mixers are connected to control channels. Each control channel has serial circuit of correlation mixer, amplifier, low-pass filter, phase detector, function generator which converts input signal according to given function, multiplier and algebraic adding unit. In addition control channel has adder, weight calculation unit, which input is connected to output of low-pass filter and output is connected to second input of multiplier. Second (adding) input of algebraic adding unit and second input of phase detector receive source control signal. Output of this unit is connected to second input of mixer. EFFECT: decreased shift and decreased distortion of main maximum when zero sequence is generated towards jam. 2 dwg
