Summary:
A numerical FDTD approach for electromagnetic scattering from an object over a randomly rough surface in three- dimensional (3D)) model is developed. Rough surface is truncated in numerical simulation by using the periodic surface extension, and one period of the rough surface with dependence of the correlation length is used for scattering computation. Generation of the incident wave upon the rough surface is presented. A numerical model and algorithm of a single object on or above a rough surface are developed. Polarized bistatic scattering from the object and rough surface is obtained based on numerical distribution of the near zone fields. Comparison with conventional two- dimensional model is also discussed.
