The thesis consists of six chapters . The first chapter describes the significance of surface emissivity and research progress . Second chapter introduces Weng et al. Complex surface emissivity mode , use this mode different surface types of surface emissivity sensitivity parameter experiments to study the changes in the law . Before Chapter of small spherical particles to the scattering cross section is derived to provide a theoretical basis for future calculations . The fourth chapter introduces a model of the dielectric constant of bound water in the soil . Soil water , soil moisture , and discussed the relationship of bound water dielectric constant and the permittivity of free water in different humidity conditions for the bound and free water , wet soil dielectric constant model . Chapter wet soil permittivity model introduced to Weng et al. Complex surface than the emissivity mode to study the changes of bare soil emissivity , and Weng et al. Complex surface emissivity mode the calculated results were compared . Chapter pointed out that the problem also exists in the study work , and made the initial ideas for future research work .
