The study of the statistical characteristics of monopulse ratio

Abstract

In many monopulse radars, the angular information of targets is abstracted from the monopulse ratio, so the statistical characteristics of the monopulse ratio influences the tracking effect directly. This paper derives in detail the mean, variance and distribution of the monopulse ratio for a Rayleigh target and explains their physical meaning. Unlike most of the previous investigation, complex DOA is taken in here to make the conclusion more generalized.
