Abstract :
A pulse-Doppler RADAR of 20 ns pulsewidth was developed and tested as an automotive collision prevention sensor. A simple but effective super-heterodyne structure was realized by the use of one FM Gunn oscillator as both the transmitter and the local oscillator. It is a unique feature of the system that the IF signal is coherent in every pulse repetition, which contributes to the realization of a pulse-Doppler system in a very simple configuration. A micro-computer is utilized in the signal processor unit which calculates danger evaluation and false alarm prevention.
