摘要：
In this paper, the fast physical optics (FPO) method based on the quadratic patches is applied to the calculation of rough surface spectrum scattering. The rough surface is based on the P-M spectral function and the Monte Carlo simulation method is used to generate the sea surface model. The rough surface is discretized by the quadratic patches, which is suitable for the calculation of physical optical scattering based on the quadratic patches. The quadratic patches discretization model can greatly reduce the number of patches compared with the plane triangle discretization, thereby effectively reducing the calculation time. Numerical examples illustrate the efficiency and accuracy of the algorithm.
