提出了一种新的条带图双基地SAR快速反投影算法。该算法从波束形式和航迹与映射区域的空间关系两方面进行了改进。与传统BP算法相比，快速BP算法具有更高的计算效率。同时又保留了传统BP算法的鲁棒性、成像精度高、对处理器内存要求小、易于并行处理等优点。点目标的成像结果和实验数据验证了快速BP算法的优越性。
In this paper, a novel fast backprojection (BP) algorithm for stripmap bistatic SAR is presented. This algorithm gets improvements from the perspective of beam form and the space relation between the flight path and the mapping areas. Comparing with the traditional BP algorithm, the fast BP algorithm has higher computational efficiency. Also, it keeps the advantages of the traditional BP algorithm, such as robustness, high imaging precision, small memory requirements in processor and parallel processing easily. The imaging results of point targets and the experimental data verify the advantages of the fast BP algorithm.
