An e-cient approach called general sparse matrix canonical grid (G-SMCG) method is proposed to analyze the electromagnetic scattering from 2-D dielectric rough surface with a conducting object partially buried. In this paper, the scattering of 3-D arbitrarily shaped object is computed by using the traditional method of moments (MoM) with RWG basis function, and the scattering of rough surface is analyzed by using the SMCG method. The coupling interactions between an object and rough surface are calculated by iterative method. Combing the ocean rough surface with Pierson Moskowitz (PM) spectrum, the bistatic scattering coe-cients of typical objects buried in the ocean surface have been computed by using the proposed method. Then the accuracy and e-ciency of this method are discussed. Finally, the bistatic scattering coe-cients of a ship located on ocean surface are calculated, and the in∞uence of sea state and wind direction on the scattering coe-cients is indicated.
