ABSTRACT:
A Doppler radar for use in a vehicle for predicting a collision with another vehicle, capable of detecting noise due to a false wave i.e., the transmitted wave from another vehicle having a frequency in the vicinity of the true transmitted wave frequency and having entered through a receiver antenna into a mixer, and controlling the frequency of the true transmitted wave to depress said noise to zero, thereby avoiding the interference of the false wave with the Doppler signal output.
