中文摘要：

作为一种新兴的星载极化SAR系统,星载简缩极化（Compact Polarimetric）SAR能同时获取目标较丰富的极化信息和实现大幅宽观测,在海洋观测领域具有先天的优势。该文针对星载简缩极化SAR海上船舶目标检测应用,首先简要介绍了星载简缩极化SAR系统基本模式及发展,其次综述了典型的星载简缩极化SAR信息处理方法,在此基础上,重点分析比较了目前常用的星载简缩极化SAR船舶目标检测方法的特点,然后给出了作者研究小组在星载简缩极化SAR船舶目标检测方面的部分研究结果,最后分析展望了进一步研究方向。

英文摘要：

Spaceborne Compact Polarimetric Synthetic Aperture Radar（CP SAR） is a new form of SAR,which has intrinsic advantages in maritime surveillance because it can obtain relatively rich polarimetric information of targets with wide swath.First,the basic modes and the development of a spaceborne CP SAR system are introduced in this paper with respect to ship detection applications.Second,typical methods of spaceborne CP SAR information processing are reviewed.Third,the attributes of frequently used methods for spaceborne CP SAR ship detection are analyzed and compared in depth.Fourth,the results of our research on spaceborne CP SAR ship detection are given.Finally,suggestions for further research on spaceborne CP SAR ship detection are proposed.
