The research on SAR imaging technology of buried object

摘要

A fast radar imaging method of detecting the buried object quickly and exactly is presented in this paper. At first, the complex backscatter data is computed by using the Kirchhoff approximation(KA) combing the boundary method(BIM). Then, a conventional synthetic aperture radar(SAR)imaging procedure called back projection method is used to generate 2-D image. The choice of window functions is researched. The random rough surface with Gauss spectrum is used to simulate the ground. The tapered incident wave is chosen to reduce the truncation error. The method presented here is highly efficient concerning computational memory, time, and versatility. The result is very useful for realistic object detecting.
