本文以SeaWinds散射计为例，从最大似然估计的海面风场反演方法出发，根据其目标函数的一般分布特征，提出并实现了一种快速风矢量搜索算法。然后采用美国SeaWinds散射计的部分LA实测数据对该搜索算法进行了验证，并与常规算法对同一实验数据的反演偏差及运行时间进行了对比分析，结果表明该算法在能够保证反演精度的前提下，在较大程度上提高了运行效率。

Based on the MLE(Maximum Likelihood Estimation) algorithm for SeaWinds scatterometer wind retrieval and according to the general distribution characteristics of its objective function,a fast wind vector search algorithm is described and realized in this paper.Using some SeaWinds L2A data,the fast algorithm is validated and compared with the ordinary one.The results indicate that the fast algorithm is more efficient than the ordinary one without reducing the retrieval accuracy.
