| 摘 要： | 针对合成孔径雷达(Synthetic Aperture Radar,SAR)序列图像,提出了基于仿真修正的序列SAR图像内波参数反演方法。该方法使用规则化长波方程(Regular Long Wave，RLW)和M4S模型数值仿真SAR序列图像中的同一列内波，并通过与实际图像的对比修正反演参数。实验表明，该方法克服了现有方法依赖于历史水文数据精度和SAR成像条件的限制，其反演结果与实测值十分接近。

| Abstract: | Aimed at retrieving internal wave parameters from a series of SAR images,this paper introduces a simulation-revision based method.This method first uses the RLW equation and M4S model to simulate the propagation of internal wave in a series of SAR images and then compares the simulation result with real SAR internal wave image to revise the retrieved internal wave parameters.Experiments show that this method overcomes the historical hydrographic data precision dependency and SAR image condition restriction of the traditional methods.The coherence between the retrieval results and in-situ data records indicates that this method has a higher retrieval precision and a wider applicability scope than the traditional methods. |
