  • To study EM scattering of a Perfectly Electric Conducting (PEC) target below the layered rough surface, a fast cross coupling iterative approach based on Bi-Conjugate Gradient (Bi-CG) method and Forward Backward Method (FBM) is presented in this paper. At first, the Electric Field Integral Equations (EFIE) of the induced currents on the rough surface and the target are derived. An iterative approach is developed to solve the two EFIE and scattering from both the target and underlying surface. The EFIE of the rough surface and the target are solved by using FBM and Bi-CG respectively. The mutual effect between the rough surface and the target are finished by iterative Calculation. The EM scattering from a metallic cylinder below the layered rough surface with two Gauss rough surfaces is computed. The result shows that the scattering coefficient is agreement with that of layered rough surfaces when the target is small enough. The relationship between the scattering pattern and the targets size and station are also discussed. Results show a buried PEC cylinder can significantly alter the scattering behaviors of layered rough surfaces.
