摘　　要：合成孔径雷达高分辨率、全天候的观测能力使其成为大面积获取高分辨海面风场的重要手段,这有助于我们理解各种海洋现象的物理过程,尤其是在海岸带,合成孔径雷达反演风场更具优势。以合成孔径雷达风向确定方式为主线,详细阐述了国内外学者在合成孔径雷达风场反演方面的研究进展,主要包括:利用影像线性纹理特征进行风场反演、基于外部初始风向的风场反演方法以及利用影像本身所包含的其它信息进行的风场反演工作,诸如距离向入射角差异、多极化后向散射等,并对合成孔径雷达风场反演的发展给出自己的观点。The high resolution and all-weather observation abilities have made the synthetic aperture radar（SAR） one of the most important ways of ocean wind retrieval in large area.This helps us understand the physics process of all kinds of different oceanic phenomena especially in coastal area where SAR wind becomes more valuable.According to the method of wind direction determination,this paper reviews the progress in ocean wind retrieval form SAR data in detail,which includes linear feature based wind retrieval,external wind direction based wind retrieval and wind retrieval from other information contained in the SAR images such as the difference of incidence angle and multi-polarimetric backscattering.Lastly,a viewpoint of the development trend of SAR ocean wind retrieval is formulated.
