Maximum Likelihood Angle Extractor for Two Closely Spaced Targets

In a scenario of closely spaced targets special attention has to be paid to radar signal processing. In this paper we present an advanced processing technique, which uses the maximum likelihood (ML) criterion to extract from a monopulse radar separate angle measurements for unresolved targets. This processing results in a significant improvement, in terms of measurement error standard deviations, over angle estimators using the monopulse ratio. …
