A new multi-static Synthetic Aperture Radar (SAR) mission concept, StereoSAR, is currently under study at the European Space Agency (ESA). It envisages a receive-only C-band dual polarimetric SAR system constituted of two satellites working in synergy with Sentinel-1. Its primary aim is to provide new, high-resolution, global observations of the ocean surface currents, also at sub-mesoscales, with temporal resolution sufficiently high to sam-ple ocean surface dynamics. The Doppler Centroid Anomaly (DCA) technique is applied in order to measure Total Surface Current Velocity vectors (TSCVs). An overview of the proposed mission concept is provided, together with the results of a preliminary performance analysis.
