Abstract

The echo signal of wide-band monopulse radar spreads in multiple range cells. Thus, effective utilization of echo signal is an important issue for this kind of radar. Based on parameter estimation model, maximum likelihood method is proposed in this paper, which collects all the energy spreading in multiple range cells. Cramer-Rao low bound of angle estimation is deduced in theory. Simulation results demonstrate maximum likelihood method which performs better than both dominant scatter estimate method and weighted estimate method.
