Abstract

The interaction of electromagnetic radiation with two-dimensional inhomogeneous dielectrics is described using a hybrid approach that has both analytical and computational elements. It is then applied to the simulation of microwave radar images. The scattered field is calculated in a composite fashion by considering separately the effects due to slant range projection and the physical interaction. By using a facet model, the simulated scattered field is related to the object structure. The statistics of the image are investigated as functions of the number of facets per resolution cell of the radar and the surface roughness, for smooth and rough surfaces and correlated and uncorrelated surfaces. The systematic behavior of the scattered intensity as a function of the target structure and composition is also discussed
