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.
