ABSTRACT:
An FM radar system includes an amplifier for amplifying the beat signal at an amplification factor varying with the frequency, and a level correcting device for correcting a spectrum level of an amplified signal or a spectrum level of a signal generated based on the amplified signal, into a spectrum level obtained when the beat signal is amplified without involving Doppler shift caused by a velocity of the target relative to the FM radar system. By virtue of the correction performed by the level correcting device, it becomes possible to obtain a real spectrum level which is observed when the target is stationary or fixed in position relative to the radar system.
