研究了主动和被动微波地形遥感。分层介质和粗糙表面的电磁波散射和发射被认为特别适用于土壤湿度的遥感。随机和离散散射体模型的辐射传输理论进行检查。建立了适用于主动和被动遥感的非球形粒子的矢量辐射传输方程。单次和多次散射的解决方案说明与遥感问题的应用。分析波动理论使用Dyson和Bethe-Salpeter方程来处理随机介质的散射。后向散射增强效应，强介电常数波动理论，和修改的辐射传输方程。研究了电磁波在密集分布离散散射体上的散射。计算了稠密介质中的有效传播常数和后向散射系数。
Active and passive microwave remote sensing of earth terrains is studied. Electromagnetic wave scattering and emission from stratified media and rough surfaces are considered with particular application to the remote sensing of soil moisture. Radiative transfer theory for both the random and discrete scatterer models is examined. Vector radiative transfer equations for nonspherical particles are developed for both active and passive remote sensing. Single and multiple scattering solutions are illustrated with applications to remote sensing problems. Analytical wave theory using the Dyson and Bethe-Salpeter equations is employed to treat scattering by random media. The backscattering enhancement effects, strong permittivity fluctuation theory, and modified radiative transfer equations are addressed. The electromagnetic wave scattering from a dense distribution of discrete scatterers is studied. The effective propagation constants and backscattering coefficients are calculated and illustrated for dense media.
