Research on the Microwave Scattering from Bare Land Based on IEM

With the development of remote sensing for the land environment, the microwave scattering of bare land attracts more attention. Comparing Gauss rough surface, the surface with exponential correlation function shows better agreement with natural environment. In this paper, the scattering characteristics of rough surface with exponential correlation function are investigated. The monostatic and bistatic scattering results simulated with integral equation method (IEM). By comparing the results of desert, gobi and soil environment at X and Ku band, the effects of key parameters on the scattering characteristics are analyzed. The research in this paper is expected to possess an application value in the microwave remote sensing for the land environment.
