摘要
基于后向散射系数反演高空间分辨率海面风场,采用谱方法确定风向,并利用CMOD4模式函数反演风速。以ERS-2 SAR黄海区域图像为例,反演海面风场,并将反演结果同QuikSCAT散射计对比,比较吻合,证明该方法在黄海区域的可行性。
Based on the principle of SAR image retrieval, a retrieval method is discussed in this paper, which 2D FFT method is used to evaluate wind direction, then CMOD4 model is used to calculate wind speed. As a case study, a SAR image in Huanghai Sea is proceeded. The results are compared with QuikSCAT data. It is shown that they are in good agreement and the method is available in Huanghai Sea.
