In this paper, a theoretioal model of microwave radiation from sea surface is set up, together with the analysis and treatment of data measured by airborne remote sensing. Based on L. T. Sang and J. A. Kong's single layer model, and making a further extension of this model to an ordinary noncoherent waves' radiation model of poly-laminated stochastic media, the author points out that the microwave radiation of sandwich media can be described by a system of linear equations and uses the sparse matrix to solve them. Based on this, the author analyzes same special models and studies the quantative relationship between penetration depth and the measuring capacity of ice thickness by using the microwave radiometer. The results show that the maximum measuring thickness is propotional to the penetration depth, and the proportional coefficient is about 1-1.5. And from the power transmission viewpoint, the corresponding physical significances are obtained. Using the optimal technigue to make a regressive analysis for the experimental results, the different treatment results for various wavebands are given and using these to compare with the calculated ones for giving their explanations.

本文建立了海冰的微波幅射理论模型,并分析和处理了航空遥感测试数据。本文以L·Tsang和J·A·Kong的单层模型为基础,将其模型进一步推广,给出了一般多层随机介质的非相干波幅射模型,指出可用一组线性方程组来描述层状介质的微波辐射,并用稀疏矩阵求得了方程组的解。在此基础上,对某些特定情况下的模型进行了分析,研究了微波辐射计探测冰厚的能力与穿透深度的定量关系。指出最大探测厚度正比于穿透深度,比例系数在1~1.5之间。同时从能量传输的角度出发,给出了相应的物理意义。还利用优化技术对实验结果进行回归分析,给出了不同波段的处理结果,同时与模型的计算结果进行了比较和解释。
