Modelling complex for surface radar images in the “distance-angle” coordinates

Abstract

The mathematical modelling software complex of monostatic radar systems is discussed in the article. It is aimed to model of typical radar scenarios with various conditions of an electromagnetic waves reflection from terrain. The received signals are used to synthesize radar images (portraits) of surfaces. The structure of the modelling complex allows studying of single-channel and multi-channel synthetic aperture radars with pulse and continuous types of modulation of signals reflected from underlying surfaces of different types. The complex can be useful to simulate radar portraits of the surrounding radar scene’s objects in the native “distance-angle” coordinates, including the nadir direction of the antenna system. The portraits for cases of front-side looking by a wide- pattern antenna in two adjacent directions are modelled and evaluated in the article.
