摘　　要：为了克服基于两层海洋的内孤立波SAR遥感仿真模型的缺陷,使用基于连续分层海洋模型的GK-dV方程,在南海东北部深水海域进行了大振幅内孤立波传播模拟,模拟输出内孤立波振幅91.0m,半波宽度262.0m。然后使用新建立的基于连续分层海洋模型的内孤立波SAR遥感仿真模型进行了内孤立波反演,反演出内孤立波半波宽度251.5m,相对输入误差为4.0%,比旧模型的34.2%有了较大改进。In order to improve the simulation results of the SAR （Synthetic aperture radar） signatures on the basis of two-layer oceanic model, the simulation of the propagation of the large-amplitude internal solitary waves in the deep northeast South China Sea was made based on a continuous stratified oceanic model using the GK-dV equation, the simulation results of the amplitude and half-width of internal solitary wave were 91.0 m, 262.0 m respectively. The simulation of the SAR signatures of the large-amplitude internal solitary waves was also made, the simulation of half-width is 251.5 m, relative error was only 4.0%, far less than the relative error of 34.2% based on the traditional model.
