| 摘 要： | 介绍一种基于一阶辐射传输的积雪散射模型。该模型考虑了积雪覆盖地表微波散射的3种回波分量： 雪层表面散射、下垫面散射以及雪层体散射。对于其中2个面散射分量，文章中应用一种新的面散射模型——AIEM取代原有的IEM模型进行处理。最后，使用Michigan大学的实测数据对改进后模型的模拟结果进行验证，并与改进前的模拟结果进行了对比。

| Abstract: | A method of snow covered ground simulation using the first -order radioactive transfer model is described in this paper. In this method, three parts of the echo are taken into account, i.e. , top surface scattering, volume scattering and subsurface scattering. A new surface scattering model AIEM, instead of the IEM model, is used to deal with the surface scattering problem. Finally, the improved method is verified using the measured data of 1995 from the University of Michigan. |
