Abstract

PURPOSE:To suppress a noiselike disturbing wave by using a gain control amplifier which varies with the level of a received input at the auxiliary channel input stage of a side lobe canceler (SLC) circuit. CONSTITUTION:The gain control amplifier 25 of the auxiliary channel system of the SLC circuit amplifies an input signal of the auxiliary channel to an almost fixed level and also performs control without causing the saturation of the input signal. The output voltage of the amplifier 25, therefore, becomes nearly fixed, so the band width of the loop of the SLC becomes fixed and the response speed of the loop can be converged at a nearly fixed speed. Then the gain is controlled with the level of the input signal, so an input wave is never saturated and the input waveform does not deform even through the amplifier, so the noiselike disturbing wave can be suppressed.
