The patent describes an improved device for detection of a Doppler signal on a background of interference. It consists basically of an existing device with a spectrum converter circuit which converts the receiver signal spectrum into one which is mirror-symmetrical about a reference frequency. It is installed between the radar receiver output and the compensation channel input. Increased probability of detection of a useful Doppler signal is claimed.
