摘　　要：文中分析了机载SAR对动目标三维成像的方案。首先说明了采用通常处理方法所存在的缺点,然后指出了"玷污"中实际包含了有用目标信息,列出了提取有用信息的系统方框图,最后重点描述了所得到的目标三维图像,并给出了具体图形。但目前的方法计算量很大,需要进一步进行研究改进。The concept of forming 3-dimensional moving target image in air-born SAR is analyzed in this paper. First, the shortcoming of using conventional processing method is explained. Then, ＂smeared spot＂ actually contains useful target information is pointed out. A system block diagram for extracting useful information is presented. Finally, the description of obtained target 3-dimensional image is emphasized, and some pictures are given. But the current method suffers from large computation load. So further research on improvement is needed.
