Analysis of electromagnetic scattering from the 3D conducting object on the random ocean-like rough surfaces

The Electromagnetic (EM) scattering characteristic from the 3D conducting object above the random ocean-like rough surfaces is evaluated by using the Method of Moment (MoM) in this paper. The vector potential dyadic Green's function and the scalar potential Green's functions are calculated of the electric dipole and magnetic dipole in the half space media. Using them in the MoM, the water sea could be regarded as the half low space medium and the sea rough surfaces could be regarded as the dielectric surfaces above the sea. The scattering characteristic of this model is calculated by establishing the integral equation of the combined conducting/dielectric objects and solving the matrix equation with the iteration method. The numerical results show the method presented in this paper is valid.
