摘　　要：应用ENVISAT-ASAR数据对南海东北部的海洋内波进行研究,用遥感方法反演得到一组内波参数,分析了海底地形变化趋势对内波传播的影响,给出内波参数据与地形变化之间的统计关系。通过分析得出内波的传播方向并不完全与海底地形变化一致。这对于前向内波理论本身和应用卫星遥感方法对内波参数获取研究具有重要意义。A study of internal waves occurring in the northeastern South China Sea with ENVISAT-ASAR data is presented. Using the remote sensing analyzing approach, a group of parameters of the internal waves is retrieved from synthesize aperture radar（SAR） image. The influence of the topographic variation on the propagation of internal waves is analyzed and the relation between the topographic variation and parameters of the internal waves is given. It is concluded that the direction of internal waves is incompletely consistent with the gradation of benthal topography and that the variation of topography on the shelf is one of the important factors of nonlinear effect on the propagation of internal waves. It is beneficial to research on internal waves＇ theory and retrieval modeling for internal waves＇ parameters using remote sensing data.
