The HRWS spaceborne SAR system can not only obtain the ocean environment parameters (such as current, wave, wide speed and direction and internal wave), but also extract a variety of target information (such as ships, oil spills and sea ice) on the surface of the sea. Therefore, the HRWS spaceborne SAR system plays an important role in the national economic development and the national defense construction. This paper reviews the applications of the spaceborne SAR system in ocean surveillance and the key techniques of the spaceborne SAR system for ocean surveillance. Finally, a possible HRWS SAR satellite constellation is designed, which can meet the demand of ocean surveillance in the future., authors=DENG Yunkai, YU Weidong, WANG Yu, authorsList=DENG Yunkai, YU

articleAbstract=为了满足对海洋监视日益增长的需求，星载合成孔径雷达（SAR）系统应具备高分辨率宽测绘带能力。高分宽幅星载SAR系统不仅能够获得海洋的环境参数（如洋流、内波、风场、海浪等），还能够获得海面上各种目标（如舰船、溢油、海冰等）的信息，为国民经济建设和国防建设提供信息来源。本文讨论了星载SAR系统在海洋监视中的应用，论述了用于海洋监视的星载SAR系统关键技术，总结了未来海洋监视星载SAR的发展方向。,
