Analysis of the Scattering Characteristics of Sea Surface with the Influence from Internal Wave

  • 摘要: 海洋内波通常在海面之下传播,并通过波流相互作用影响海洋表面毛细波的分布,在合成孔径雷达(SAR)图像中表现为亮暗相间的纹理.该文首先基于Korteweg-de Vries(KdV)方程,建立内波传播模型;通过波流相互作用函数,基于波作用量方程,对表面毛细波的波谱进行修正;最后基于双尺度方法的面元模型,将内波对高频谱的修正作用考虑在内,计算内波的存在对大尺寸海面电磁散射特性的影响.文中计算了内波存在时海面散射系数分布,分析了不同的内波参数,不同海况参数等对海面散射系数和多普勒的影响.
