| 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. |
