Abstract In this paper, the shortcomings of traditional methods for wave motions removing are analyzed and an iterative method for ocean surface current retrieval by Along-Track Interferometric SAR (ATI-SAR) based on a microwave ocean imaging simulation model is developed. This iterative model is used to obtain the ocean surface current using the JPL AIRSAR ATI-SAR data. The retrieved surface current is compared with the output of Princeton Ocean Model (POM). Both surface currents are in good agreement with each other, which proves the effectiveness of this iterative inversion method.
