A reflex klystron oscillator is used as the microwave transmitter and superregenerative receiver in a doppler radar designed to measure the relative speed of a moving target at distances of up to three hundred feet. Experiments are described which relate the sensitivity of the system to the change in oscillation frequency occuring during the quench cycle; in particular, by using a resonator quench, the effective power of the receiver is increased by over 50 db above that obtained with a repeller quench. Road tests of the receiver have shown it to be of value as part of a collisionwarning device for road vehicles.
