Abstract:
1. An FM-CW radar system which frequency-modulates a voltage-controlled oscillator by applying thereto a modulating signal from a modulating signal generator, and which transmits a frequency-modulated wave by time division ON-OFF control and receives a reflected wave by time division ON-OFF control, said system includes means for varying a frequency used to perform said time division ON-OFF control, and means for discriminating between a signal component varying in response to the variation of said frequency and a signal component not varying in response to the variation of said frequency, said discriminating means discriminates a signal component varying in response to a variation of the frequency as a signal component related to a target object, and discriminates a signal component not varying in response to a variation of the frequency as a signal component not related to a target object.
