Title: Shipborne Inverse Synthetic Aperture Radar Imaging of Ship Target

Abstract: Shipborne Inverse synthetic aperture radar (ISAR) imaging of target with complex motion is very important and difficult in the field of radar imaging, and it has great value in practice. For the target with complex motion, the rotational velocity and rotational axis are time varying, and this will induce the time varying character for the Doppler frequency of the received signal. Thus, the traditional radar imaging algorithm will be inappropriate in this case, and the corresponding radar images will be blurred severely and can not be recognized correctely. Then, the received signal can be characterized as multi-component polynomial phase signal (PPS) for the target with complex motion, and the time frequency analysis for the PPS should be implemented to improve the radar image quality. This report will introduce the principle of shipborne ISAR imaging of ship target, and some experimental results for the raw data are provided. Finally, the prospect or vision for the ISAR imaging of target with complex motion in the future is given.
