| 摘 要： | 基于驻相近似下得到的考虑遮蔽效应时的粗糙面散射一、二阶基尔霍夫公式,研究了满足半经验海谱分布的二维介质粗糙海面的电磁散射,分析了海面散射出现后向增强效应的条件,计算了不同极化状态的散射系数角分布,并进行了比较,详细讨论了二阶散射系数角分布及后向增强效应随风速、入射频率和入射角的变化规律.

| Abstract: | Based on the formulae of the first-order and second-order Kirchhoff approximation of rough surface scattering obtained from the stationary phase method with consideration of the shadowing effect,the electromagnetic scattering of the two-dimensional rough sea surface with the semi-empirical sea spectrum was investigated.The condition of the backscattering enhancement occuring for the sea scattering was analyzed.The angular distribution of the scattering coefficient was calculated and compared for different p... |
