摘要

基于文氏改进功率谱和Donelan方向分布的实验结论，结合经典的Monte Carlo法提出了一种适用于不同水深、不同风浪成长阶段的二维粗糙海面模型. 在经典的双尺度法计算海面后向散射的基础上，结合小斜率近似法的仿真结果，对电磁散射计算方法进行改进. 通过与典型海杂波均值散射系数GIT模型的拟合结果进行对比，验证了文氏改进谱在中国近海海面模拟的适应性与改进后电磁散射计算方法的有效性.

By combining the improved Wen's spectrum with the classic Monte Carlo algorithm and Donelan's experimental conclusion, a two-dimensional sea surface model suitable for different depths and different stages of wave growth is proposed in this paper. Based on the classic two-scale method for the calculation of sea backscattering coefficient, and the introduction of the simulation results obtained by the SSA (small slope approximation) method, the electromagnetic scattering calculation method is modified. Compared with the fitting result based on the backscattering coefficient model of GIT, it proves that the improved Wen's spectrum is suitable for Chinese coastal waves, and the proposed electromagnetic scattering theory is accurate and efficient.
