本文给出了海洋二号（HY-2）卫星雷达高度计风速反演的双参数算法模型，并利用Jason-1 产品和HY-2 卫星微波散射计产品定性验证了双参数算法模型的正确性，同时利用星星交叉比对方法、美国国家浮标数据中心（National Data Buoy Center，NDBC）浮标数据验证方法、美国国家环境预报中心（National Centers for Environmental Prediction，NCEP）再分析数据验证方法三种不同方法对该模型进行定量化验证，结果表明HY-2 卫星雷达高度计风速反演的双参数算法模型的反演精度达到2.0 m/s 的精度，满足海洋业务应用和科学研究的精度要求，可为用户提供满足观测要求的海面风产品。

Sea surface wind speed has a very important role in the transfer of kinetic energy in the ocean, and the exchange of the matter and energy in the air-sea surface. The HY-2 satellite altimeter provides sea surface height, significant wave height, sea surface wind speed. And the accuracy of the wind speed affects the users’ application. In this study, the two-parameter algorithm is used to get the wind speed from HY-2 satellite radar altimeter. The correctness of this algorithm is calculated using the Jason-1 and HY-2 scatterometer data qualitatively. Three different methods(cross-over method, NDBC) are used respectively to evaluate this algorithm.
