Software Complex for Modeling the Work of Multichannel SAR in Wide Range of Application

The methods for modeling signals reflected from an underlying surface in wide conditions of operating of synthetic aperture radars (SAR), which aimed to radio navigation of different aircrafts, is discussed in the article. Here, the structure of the software complex for multichannel SAR modeling is offered. The main features of the SAR model realized in the MATLAB are the ability of synthesizing of radar images by vertical irradiating of an underlying surface, and also a wide variety of natural terrain surfaces and two base types of probing signals (pulse and continuous waveforms). This paper also contains some estimated results and examples of modeling and computing radar images of a surface in specific distance-angle coordinates. This software complex allows us to model the reflected signals which than can be processed by common SAR technique to compute surface radar images for one- and multichannel SAR’s receiver for vertical and side-looking surface observation.
