摘　　要：平台轨道及姿态误差模型是星载SAR数据模拟及相应的模拟系统的关键组成部分.简要分析了机载SAR和星载SAR的差异,重点对星载SAR的平台轨道及姿态模型进行了分析,最后对星载SAR回波信号仿真方法进行了分析.Accurate orbit and attitude model is of great importance to data and system simulation of space-borne SAR. Following a brief analysis of the difference between air-borne and space-borne SAR, the paper analyzes the simulated orbit and attitude model of space-borne SAR. Finally, analysis is given on the simulation method on the echo of space-borne SAR.
