たことを特徴とするＦＭ−ＣＷレーダ。 、A continuous wave CM frequency-modulated by an FM modulator is transmitted from a transmitter to a target, and the reflected reception wave from the target is input to a receiver mixer, and the branched output of the FM modulator is added to perform homodyne detection to generate a distance signal. In the FM-CW radar for detection, an amplitude correction circuit consisting only of passive circuits is installed on the line that applies the branch output of the FM modulator to the receiver mixer to correct the amplitude deviation based on the frequency characteristics of the skeleton-branch output. An FM-CW radar characterized by the following. ,
