The Image Plane Analysis and Echo Model Amendment of Bistatic ISAR

摘要

摘要: 该文分析了双基地逆合成孔径雷达的成像平面。采用基于双基地SAR成像平面分析，双基地目标旋转矢量分析两种方法，分别建立了两种不同的双基地ISAR成像平面模型。为验证模型正确性，分别将两种模型应用于双基地转台成像分析，并仿真验证。成像仿真结果表明了旋转矢量分析法建立模型的正确性。基于成像平面分析，研究了双基地转台模型的适应性，修正了常用的双基地ISAR散射点回波模型，验证了修正回波模型的正确性，并针对不同的目标运动情况，给出了成像平面的估计算法。

Abstract: This paper discusses mainly the image plane of the bistatic ISAR. The image plane is modeled by two different methods separately. One is modeling the image plane according to the bistatic SAR image plane; the other is to model the plane by target rotation vector analysis. The modeling process is presented in detail. They are then testified by applying them to interpret the bistatic turntable imaging. The simulation results show the validity of the second model. Based on the image plane analysis, the application condition of the turntable imaging model is analyzed. And the common used bistatic ISAR echo model is modified. Simulation results show the validity of the modified model. Finally, the image plane estimation method is also given according to different target motion situation.
