| The scattering properties of random rough surfaces are detectable and identifiable. To solve many issues about theory and engineering, the scattering of random rough surfaces needs to be researched. The theoretical research on the light scattering characteristics of two-dimensional random rough surface is conducted.The background of the scattering problem, significance and the state of the art of the research are outlined. Light scattering is introduced through the analysis on the related parameters of the random rough surface. In the light of Huygens Principle the single scattering model of two-dimensional rough surface is established. The model is based on the existing scattering theory-Kirchhoff approximation, which is tangential plane and stationary phase approximation method. The shadowing effect on the scattering coefficient is also considered in the scattering model. The relevant parameters'influence on single scattering coefficient under different polarization cases is analyzed. A model for double scattering based on single scattering model is established. A new method is proposed to deduce the second scattering coefficient of random rough surface, where the scattering wave of the first scattering is considered as the incident wave of the second scattering. The influence of relevant parameters on total scattering coefficients including second scattering is analyzed, and the results are analyzed in comparison with the single scattering. The results from our study are compared with the published experimental data. |
