摘要：

A multi-hybrid method combining numerical vector finite-element method/boundary integral method (FEM/BIM) and analytic Kirchhoff approximation (KA) is employed in this paper to study the scattering from a 3-D object above a 2-D conductive rough surface. The scattering from the target is studied by hybrid vector FEM/BIM while KA is applied on the underlying rough surface to reduce the computation time and memory requirement. An iterative approach is employed to take into account the multiple interaction between the target and underlying rough surface. Using the Monte Carlo method to generate 2-D Gaussian rough surface, bistatic difference field radar cross section (d-RCS) of A 3-D dielectric target above a 2-D conductive rough surface is numerically simulated.
