提出了一种利用卫星高度计测量的同步双波段雷达射雷达散射截面数据提取海面风速特别是高风速信息的补偿算法。这一方法的基本思想是假定在正常情况下，高度计测量的Ku和C波段的后向散射截面对于某一风速存在一种“标准”关系，降雨和大浪等异常大气海洋过程的出现会导致σ＾Oku/

Based on simultaneous measurements of Ku and C bands' radar cross sections (σ0Kuandσ0C) from satellite altimetry, this paper proposes a dual-frequency approach to enhance the performance of existing wind speed algorithms, especially at high wind speeds. A simple scheme ofσ0Ku/σ0Cadjustment is developed, assuming that altimeter measured radar cross sections of Ku and C bands follow a“standard”relationship for various wind speeds under normal conditions. Rain and significant wave height(SWH) induced systematic deviations ofσ0Ku/σ0Cwith respect to their“standard”positions are observed and corrected using the proposed scheme. Validation of our results against buoy observations suggests that the dual-frequency scheme improves the accuracy of altimeter measured sea surface wind speeds by nearly 10% compared to single frequency algorithms.
