Abstract : The patent describes a radar where the CW transmitter oscillator is periodically phase modulated by means of a pulse generator. The echo signals are combined with a sample of the transmitted signals and applied to a single mixer. A pair of Doppler signals are sequentially derived from the mixer output. The phase relations of these Doppler signals determines the direction of radial target velocity and the range can be obtained from the setting of a variable delay line connected to the pulse generator.
