一种修正的星载散射计反演海面风场的场方式反演算法
国家海洋局第三海洋研究所,福建厦门361005
摘要:

由于卫星散射计探视雷达回波的各向异性的双调和性质,同时由于散射物理模型函数的非线性及信号中存在噪声,使得常规点方式风场反演中风向有多至4 个解的多解存在。给出了一种改进的场方式反演方法,利用该方法从卫星散射计测量的后向散射强度的数据中唯一反演出大尺度海洋风场。通过数值模拟和实际算例计算表明反演结果在风向、风速上都与真解是吻合的。从结果可以看到,所采用的改进的场方式反演方法对模拟数据或真实散射计探测海面风场的反演是成功的。

A Modified Model Based on Estimation of Sea Surface Wind Field from Spaceborne Scatterometer
Abstract:

Owing to the anisotropic and the biharmonic nature of microwave radar backscatter on spaceborne scatterometer, and to the scatter model function nolinear and the existence of various noise sources in the measurements in addition to the model function, the retrieval wind results consist of as many as four wind directions. We introduce a modified model approach to estimate the unique synoptic oceanic wind field from backscatter of spaceborne scatterometer. The comparison those estimated from numerical simulation with real data shows the agreement largely in wind direction and in the true wind speed. It is demonstrated very successfully that the simulated or real scatterometer data with the modified model estimation has been retrieved in this paper.
