VVP三维风场反演方法研究

A study of VVP algorithm for 3D wind retrieval

在研究了现有气象雷达三维风场反演的VVP方法的基础上,提出了一种新的基于三维风场均匀分布假设的三维风场VVP反演算法.采用提出的算法,进行了模拟风场和雷达实测风场的反演实验.按照实验结果进行了反演误差分析.理论和实验结果证明采用风场均匀分布假设的VVP方法,反演的三维风场与雷达实测的三维风场比较吻合.

On the basis of studying the existing VVP theories and algorithms, a new method of VVP algorithrn is proposed for meteorological radar wind 3D retrieval. The method is under the assumption that a 3D wind field is locally homogeneous. Applying the method proposed, experiments of 3D wind field retrieval have been done with both simulated wind data and radar detected real wind data. Retrieval error analysis of the experiments has also been carried out. The theory and the experimental results show that using the new VVP algorithm under the assumption of local homogeneous 3D wind field, the retrieved 3D wind field is comparatively conform to the radar detected real 3D wind field.
