摘要：
This paper implements the method of moment and physical optics hybrid method in calculating scattered field from complex multi-scale scatterers. The numerical steepest descent path (NSDP) method is introduced to calculate high oscillatory PO integrals. As for acceleration, we introduce GPU's rendering and zbuffer shadowing to accelerate the lit judgement and the MPI structure to fast calculation. A vessel with the sea surface is chosen to validate the result.
