The wave is one of the important marine dynamic environment parame-ters.Up to now,TerraSAR-X is the X-band synthetic aperture radar sensor that the only way to obtain the high resolution image.Researching how to get real-time and accurate wave infor-mation from TerraSAR-X image,and use it to monitor Beibu Gulf information has important significance.[Methods]This thesis gets the information of ocean wave based on the Geophysical Model Function(GMF)for sea surface wind field and the wave parameterized early speculate spectrum retrieval model,uses HH-polarization model verifying the TerraSAR-X image in Bei-bu Gulf with practical examples, and compares the retrieval results with the operation results obtained from Wave Watch Ⅲ model.[Results]The absolute error of significant wave height is 0.8m,and the absolute error of average period is 1.9s.[Conclusion]This method can effectively extract the wave parameters from TerraSAR-X images.
