ABSTRACT:
A switching type FM-CW radar, the type of FM-CW radar improved to reduce FM-AM conversion noise, is further improved to reduce interference by radar waves from other vehicles and echo waves returned from them. A switching circuit is provided at the transmitter side, and its switching frequency is set at a different value for each individual vehicle. Furthermore, the switching frequency of an interfering wave is measured, in accordance with which the switching frequency of the switching circuit is changed.
