| 摘 要： | 本文采用数值仿真的方法,在双尺度海浪模型下,在计算机上进行了电磁波与海浪相互作用过程的数值实验。计算了VV和HH极化波散射系数与入射角度、风速、风向等海况参数间的关系,并将计算结果与美国海军研究实验室（NRL）的四频率雷达测试数据做了比较,我们的结果比N.W.Guinard and J.C.Daley计算结果有明显改进。

| Abstract: | This paper applies numerical simulation method to study the interaction process between electromagnetic wave and two-scale wave of sea surface in computer.We have computed the scattering coefficients of VV-polarization and HH-polarization waves, and their relations with angles of incidence, wind speeds, wind directions etc. of the sea states. Also, we have compared our result with experimental data for NEL 4FE. It seems that our result is better than N. W. Guinard and J. C. Daley's result. |
