Detection of unresolved targets for plane array radar based on monopulse ratio

Abstract

Detection of unresolved targets is an important prerequisite to the resolution of unresolved targets. This paper points out the difference of monopulse ratio between a single target and unresolved targets. After approximate analysis of the monopulse ratio distribution, unresolved targets detector for plane array radar is put forward. Numerical experiment results demonstrate the performance of the proposed method.
