Abstract Amodel consisting of the KdV Equation, Action Balance Equation and Bragg Scattering Model was established based on synthetic aperture radar (SAR) imaging mechanism for internal waves to retrieve internal wave depth and amplitude. Methods for internal wave depth and amplitude calculation were derived from this model. Imagery from ERS-1 SARwas used as case studies in seas around China. Comparison with in situ measurements shows that the methods are reasonable.
