The patent describes a continuous wave radar set in which the transmitted wave is periodically gradually reversed in phase by frequency modulating the microwave oscillator thereof. The target echoes are heterodyned with a sample of the transmitted wave and applied in parallel to an all-range channel and a ranging channel. Doppler frequency signals from all moving targets within the radar beam appear in the all-range channel, whereas in the ranging channel Doppler frequency signals from the two channels, or a pair of signals from the ranging channel, target range and directivity information may be obtained.
