ABSTRACT

Since GEO SAR measured data are not available at present, all the echo simulation of GEO SAR is of great significance. However, the current research mainly focuses on the truth of the point target, and the research on the distributed targets is very few. Therefore, this paper focuses on the fast echo simulation of the distributed targets and the corresponding high resolution imaging technology under the GEO SAR system. Firstly, a geometric model of the surface object scene is established. Then an improved scene RD- ACS imaging algorithm is proposed for distributed targets scenes. Finally, the correctness of echo simulation and imaging is verified by experiments.
