| 摘 要： | 机载双站SAR收、发分置,收、发平台产生的运动误差是独立的,增加了双站SAR运动补偿技术的复杂性.文中建立了平飞模式的双站SAR运动误差模型,在双站模型等效到单站的基础上,对双站SAR运动补偿方法进行了研究,基于模型等效的思路提出了基于回波数据运动补偿的方案.并讨论了PGA自聚焦算法的可行性,给出了相应的计算机仿真.

| Abstract: | Bistatic SAR uses separated transmitter and receiver flying on different platforms,and the motion error resulting from the different platforms is independence,which increases the complexity of motion error compensation.This paper firstly describes the special case of equal velocity vectors and parallel flight paths of transmitter and receiver,and makes mathematical study on motion error of the receiver and transmitter,and then the approximate bistatic-to-monostatic application is given.Based on the bistatic... |
