Abstract

The performance of a monopulse estimator depends on its monopulse ratio (MR) curve. To improve its performance, a mathematical expression of the MR curve associated with the parameters of a beamforming array is needed. In this paper, a closed-form expression for a maximum likelihood (ML) based monopulse ratio (MR) curve in a uniform linear array (ULA) monopulse radar is derived mathematically. Moreover, an approximate expression for the closed-form is presented. The validity of the closed-form derivation and its approximation is demonstrated through simulation.
