Abstract :
Angular glint gives rise to random pointing errors, which can deteriorate the direction-of-arrival (DOA) estimation accuracy. In monopulse radars the glint manifests itself through a complex valued process known as the complex monopulse ratio (CMR). Physical and statistical properties of the glint are considered. It is proposed to use the Poynting vector formalism for the CMR physical interpretation. The complex probability density function (pdf) and correlation function of CMR are derived.
