为了研究星载双基地SAR的成像算法问题，需要模拟实际场景的回波数据。在点目标模拟的基础上，提出了一种利用机载SAR灰度图像数据模拟星载双基地SAR原始回波数据的方法。首先，对机载SAR图像的灰度数据进行叠加和平均，计算不同目标的RCS。然后，利用星载双基地SAR场景回波信号模型生成实际场景的原始数据。最后利用BP算法对回波数据进行成像处理。成像结果验证了该仿真方法的正确性
ln order to research imaging algorithm problems of space-borne bistatic SAR, it is necessary to simulate echo data of actual scene. On the basis of point target simulation, a method of simulating space-borne bistatic SAR raw echo data utilizing gray image data of airborne SAR is presented in this paper. First of all, gray data of airborne SAR image is added and averaged to compute different targets RCS. Then, raw data of actual scene is generated using the model of scene echo signal of space-borne bistatic SAR. Finally, imaging processing is fulfilled utilizing BP algorithm toward echo data. The imaging result verifies the correctness of this simulation method
