在合成孔径雷达信号处理理论的基础上，提出了复杂真实场景的SAR原始数据信号的模拟方法，因而可以利用二维FFT的快速算法计算SAR原始数据的算法。并用这种方法进行了仿真，验证了其正确性和实用性。

A method for simulation of raw data for SAR true scene is advised, which is based on signals processing theory of SAR. Therefore, the 2-dimension FFT algorithm is used to calculate the raw data of the SAR. We simulated the raw data with this method and demonstrated its validity and practicability.
