摘　　要：研究了星载SAR对舰船高分辨成像的难度和方法。在星载SAR舰船数据获取模型的基础上,着重分析了舰船航行以及船体在特定海情时三维转动对星载SAR成像的影响,研究了星载SAR舰船数据的ISAR成像方法,并给出成像算法流程,仿真结果验证了该方法的有效性。This paper studies the problem and method of high-resolution ship imaging of space borne SAR. Based on the data-gathering model, this paper analyses the effect of ship sailing velocity and three-dimension rotation movements on SAR imaging, studies the ISAR imaging method to process the space borne SAR data, and then presents the arithmetic flow. The simulation results prove the validness of the above analysis.
