The Along Track Interferometry (ATI) technique has been experimented on a RAMSES X-band radar dataset to estimate river surface currents. The study areas were over the Rhone river. This paper describes the RAMSES radar dataset that has been acquired and results obtained applying ATI technique. The surface velocity maps are analyzed and then discussed as a function of the wave polarization state and the incident angle (from 40deg to 80deg). ATI measurements are consistent with ground measurements that have been done simultaneously to the RAMSES radar data acquisitions. Such river surface velocity maps could then support hydrologists numerical models.
