Then the relationship between facet number and correlation coefficient was analyzed.

The simulation method is firstly to model the ground scene using facet model,secondly to simulate backscattered signal according to system geometric model and signal model,and thirdly after imaging to carry out interferometric processing of two complex images.

A new method is proposed based on fractal theory, facet model and clutter scattering characteristic model.

In bistatic SAR raw data simulation of ground scene, the algorithm of computing bistatic backscatter coefficients of ground scene is discussed with the facet model and Kirchhoff bistatic backscatter model.

This method not only imported and improved the facet model which was usually used in SAR signal simulation method,but also studied shadow features of SAR image and gave an efficient method of judging shadow regions.

Adopting the scaling functions of Daubechies wavelet as interpolation functions of element, a wavelet element used to analyze the deformation and proper vibration of beam on elastic foundations was constructed.
