摘要 推导了BiSAR的dechirp公式,建立了BiSAR的回波信号模型,分析了BP成像算法的原理和运算效率,给出了BP成像算法的主要步骤。当双基地角为90°时,进行了仿真。通过对点目标PSF定量分析,验证了BP成像算法在BiSAR下具有良好的聚焦效果。 This paper derives the dechirp formula of bistatic SAIL The echo signal model is presented. The imaging formation and computation effective of back projection are analyzed. The main steps are also given. When the bistatic angle is 90, the simulation experiments are conducted. With the quantitive analysis of point spread function, the back projection algorithm for bistatic spotlight SAR is validated.
