极化SAR在海洋探测中的应用与探讨

Discussion on Application of Polarimetric Synthetic Aperture Radar in Marine Surveillance

合成孔径雷达(Synthetic Aperture Radar,SAR)是重要的对地观测传感器,在陆地和海洋中都有广泛的应用。极化合成孔径雷达通过不同的收发通道组合,能够获取丰富的目标散射信息,可以提升目标检测、分类识别、定量反演的能力。该文以海冰、舰船、溢油、海浪、内波、风场、海底地形等海上目标和海洋动力环境要素为例,分析了极化SAR在海洋监测中的重要作用,探讨了极化SAR未来的发展方向,给出了进一步开展极化SAR海洋应用的建议。

Synthetic Aperture Radar（SAR）,an important earth observation sensor,has been used in a wide range of applications for land and marine surveillance.Polarimetric SAR（Pol SAR） can obtain abundant scattering information of a target to improve the ability of target detection,classification,and quantitative inversion.In this paper,the important role of Pol SAR in ocean monitoring is discussed with factors such as sea ice,ships,oil spill,waves,internal waves,and seabed topography.Moreover,the future development direction of Pol SAR is put forward to get an inspiration for further research of Pol SAR in marine surveillance applications.
