利用风浪经验模型从高频地波雷达(HFSWR)的回波谱数据中反演风速需要有效波高等先验信息，因此风速的反演受有效波高反演精度的影响。该文基于风浪经验模型，利用风速和高频地波雷达海面回波二阶谱与一阶谱能量之比的关系，发展了无需波高信息的风速直接反演的经验模型。将风速反演经验模型应用到高频地波雷达风速的反演中，对两部不同频率的雷达在不同海域获得的数据进行了比较分析，结果表明，该文中采用的经验模型能够有效地对风速进行反演，其中三参数模型的结果略好于双参数模型。

The information of the significant wave height is needed in the wind speed inversion from the sea echo of High Frequency Surface Wave Radar (HFSWR) by using the empirical model of wind waves. Therefore, the accuracy of the significant wave height has an effect on the wind speed inversion. Based on the empirical model of wind waves, a wind speed inversion empirical model for wind retrieval without the information of wave height is developed, which uses the relationship between the wind speed and ratio of second-order to first-order spectrum energies. The inversion model is applied to the wind speed extraction. And the data obtained from two radars with different frequency in different detecting area are analyzed. The results show that the proposed model can be used to extract the wind speed from the HFSWR sea echo and the results of which three-parameter model are better than the two-parameter model.
