Accurate and Efficient Simulation Model for the Scattering From a Ship on a Sea-Like Surface

An accurate and efficient simulation model is developed for the scattering from a 3-D ship on a 2-D sea-like surface. The ship on the sea-like surface is modeled as a ship on a random surface with the impedance boundary condition. A full-wave simulation method is developed to simulate this model by using the self-dual integral equation and the parallel multilevel fast multipole algorithm. The simulation model is compared with the model of a ship on a flat surface and on a perfectly electrically conducting random surface, respectively. The application ranges of these models are concluded. Furthermore, the characteristics of the ship on a sea-like surface are studied by using the developed simulation model.
