Abstract

PURPOSE:To make a residual interference wave resident by that resulting from the control error only by preventing a component being the result of modulating the interference wave by a low frequency oscillator from not being leaked to the output of a desired wave signal. CONSTITUTION:A vector modulator 41 applying low frequency modulation to a received interference wave of an auxiliary antenna 2 and a vector modulator 42 controlling the amplitude and phase of the received interference wave of the auxiliary antenna 2 are provided. Only an output of the vector modulator 42 controlling the amplitude and phase of the received interference wave of the auxiliary antenna 2 is synthesized onto the received signal of a main antenna 1 so as to make the component subjected to low frequency modulation unleft in the received signal by the auxiliary antenna 2 as the residual interference wave. Thus, the interference wave invaded in the main antenna 1 for receiving a desired wave is canceled.
