| 摘 要： | 在分析SPECAN成像处理算法基础上，应用ECS算法进行ScanSAR距离向处理，ModifiedSPECAN算法进行方位向处理，完成ScanSAR精确成像处理。给出了对Burst图像内和子测绘带间Burst图像方位向像素间隔归一化方法，通过计算沿距离向的方位尺度变换因子实现整个测绘带方位向像素间隔的归一化。最后通过对点目标计算机成像仿真，验证了算法的有效性。

| Abstract: | In this paper a new algorithm for ScanSAR precision imaging is presented based on the analysis of the original SPECAN algorithm, which takes ECS in the range processing and completes azimuth processing with modified SPECAN. A method is given to normalize the azimuth pixel spacing in inner-burst by calculating the azimuth scaling factor, in which the normalization of inter-bursts is under consideration. The computer simulation for point target is carried out to validate the algorithm. |
