Replacement of a Complex Radar Object by a Two-Point Model

Abstract

The problem of modeling angular noise of distributed radar objects is considered. Analytical expressions determining the correlation functions of angular noise of a multipoint object and of its geometric model composed of virtual radiators are derived. Conditions under which these correlation functions are equal to each other are obtained. It is shown that the geometric models composed of virtual radiators are able to adequately replace reflections from distributed radar objects, i.e., the correlation functions and the angular noise distribution functions of the object and the model are equal.
