Abstract :
In this paper, some simulation results of 3D imaging of ground moving target are presented. Chirp stepped-frequency signal is transmitted in the interferometric inverse synthetic aperture radar system. Before the processing of 3D imaging, the strong ground clutter has been removed by using a new chirp stepped-frequency signal format. Then the 3D images of the ground moving targets can be achieved according to the principle of the interferometric 3D imaging.
