N2 - In this paper, a feasible simulator is proposed to predict the electromagnetic (EM) scattering from three-dimensional (3-D) electrically very large ship-sea models which are formulated accurately with surface integral equations. The EM coupling between the object and the rough surface is considered by the surface integral equation with the Green's function. In theory, standard the Method of Moments (MoM) can be used to solve the unknowns both on the object and the rough surface. However, the discretization of the rough surface significantly increases the computational resource requirements compared to calculating the scattering from the object alone. With an efficient parallelization of Multilevel Fast Multipole Algorithm (MLFMA) on computing platforms using distributed-memory architectures, the composite scattering characteristic of 3-D electrically very large ship-sea model is investigated, and a series of useful conclusions are also obtained.
