Scattering of Two-Dimensional Sea Surface at Low Grazing Angles with Physical Optics Method

摘要：

　　As the classic analytical methods cannot calculate the electromagnetic scattering characteristics at Low Grazing Angle (LGA),a novel numerical method is presented by utilizing the Radar Cross Section (RCS) of the low grazing two-dimensional PM sea spectrum based on the triangles-based Physical Optics (PO) method in this paper.The calculated RCS is compared with the numerical calculation method of different targets and frequencies of incident wave.The results show that PO method is more accurate,especially under LGA condition,and it has a better agreement with the results calculated by commercial software FEKO.
