Robust Model for sea surface current simulation from radarsat-1 SAT data

This paper was utilized robust model to simulate sea surface current pattern. The horizontal surface velocity model was modified based on the Doppler frequency theory to model the sea surface current velocity. The robust model was implemented on the SAR image at two different modes (Wide- 3 and Standard-2). The results of the study were validated using real time ocean current measurements by using AWAC equipment. It was found that the velocity and direction of the current changed through the period of the study according to the changing of Doppler frequency shift used in the model to extract the sea surface current velocity and direction from the two SAR images. At the inshore area, the velocity of current extracted based on the Wide-3 mode varied between 0.22 m/s to 0.25 m/s with the average of 0.24 m/s, while based on the Standard-2 mode it varied between 0.52 m/s to 0.65 m/s with an average velocity of 0.56 m/s.
