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.
