Tidal Current Measurement with TerraSAR-X Along-Track Interferometry

In this paper we describe new achievements of surface current measurements obtained by space-borne Along-Track Interferometry (ATI). We show how tidal currents can be mapped using the TerraSAR-X satellite and adequate dual-channel SAR data processing techniques. We present results from tidal currents at the Orkney Islands that clearly demonstrate the potential and suitability of the method
