Abstract :
On the condition of amplitude-comparison monopulse radar system, for measuring the direction of multicomponent sources in the space which have same modulation format, an algorithm of Direction-of-Arrival (DOA) estimation based on Radon-Ambiguity Transform is proposed. The typical signal model is built up, and when the time-of-arrival is very approximate, it is discussed how to extract the signal amplitude of each source. And then the algorithm´s results of angle measurement is given.
