Abstract	The along-track interferometry (ATI) SAR measures the Doppler shift of the backscattered signal and thus the line-of-sight velocity of the scatterers. This interferometric velocity is the sum of the orbital motion of water particles from the swell, phase velocities of the Bragg waves, and ocean surface currents. While the advent of ATI SAR provided us with a potentially powerful technique for ocean current mapping, the surface currents cannot yet measured exactly from interferometric velocity measurements. In this paper, we will apply a new method of extracting the surface current velocity from multiple-frequency (L- & C-band) ATI SAR data. We have tested ATI SAR data that were collected during the PACRIM-II AIRSAR experiment over the Ulsan coast on the southeastern part of the Korean peninsula. We have investigated the ocean waves and current features and have retrieved dominant ocean wave information. Furthermore, we could differentiate the ocean current and the Bragg wave phase velocities using multiple-frequency (C & L-band) ATI data.
