The image plane analysis and echo model amendment of bistatic ISAR

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.
