Distributed Target''''s Raw Data Simulation of Spaceborne SAR
星载SAR分布目标原始数据模拟研究

A method of simulating distributed target's raw data of spaceborne SAR is given. Based on the theory of Kirchhoff approach and facet, the algorithm of computing the facet's backscatter coefficients is discussed. Then the echo signal model of the distributed target consisted of facets is introduced. And the method and whole procedure of simulating distributed target's raw data are described. After the analysis of the compressed image of raw data simulated, the conclusion can be reached that the method of simulating raw data of distributed target is right.
