摘要

针对双尺度模型和直接发射率模型求解粗糙海面的亮温特点

提出了一种新的高阶Stokes向量模型。该模型基于二维粗糙海面上场的高阶微扰法展开近似

得到了4个发射率分量及亮温的高阶微扰解。通过考虑海面特性的修正

定量计算了复折射率、风速和泡沫等因素对亮温的修正效应。数值计算和测量值的比较表明

该模型是有效的。

Abstract

On the basis of analyzing the characteristic of two-scale model and direct emissivity model

a new model named high-order Stokes vector model is presented.The four Stokes components of brightness temperature and emissivity are solved using the high-order small perturbation method（HSPM）.The modified effect by the complex index of refraction

wind speed and foam is quantitatively analyzed.Compared with a set of measured data

numerical computations of the brightness temperature by moment method and HSPM for actual rough sea surface are given.The results show that the new method is validity.
