Abstract :
This paper describes a comparison study of surface scattering models and a numerical model for dielectric surfaces. Two surface scattering models namely the integral equation model (IEM) and the small slope approximation (SSA) model are used to calculate the backscattering coefficients of rough surfaces and the results are compared with numerical simulations based on the moment method (MoM). Analysis of the results obtained is also presented
