Abstract

PURPOSE:To obtain optimum reception pattern, by extracting the interference wave component from the signal obtained from a plurality of antennas and receivers and controlling the synthesized vector of a plurality of signals from the receivers. CONSTITUTION:Signals from a plurality of reception antennas 1a-1c are lowered into an intemediate frequency at down-converters 2a-2c, they are distributed at a distributor 3 into two, other two IF signals are phase-shifted by 90 deg. at vector synthesizers 6a, 6b and the amplitude is controlled at an operation control device 11 to output an arbitary vector value. When the three signals are synthesized at a synthesizer 7, the synthesized pattern is a function of the vector synthesis of the receiver of each system and it is fed to a coupler 9 through the next switcher 8. A part of the outputs enters an interference wave detector 10, the interference wave component is converted into a voltage, which is input to an operation controller, where the vector synthesizers 6a, 6b are controlled so that the interference wave component can be minimized with a fixed or more amplitude, to decrease the interference wave level.
