摘要

We present a new mission concept, referred to as StereoSAR, with as primary aim to measure ocean surface currents at sub-mesoscales. To improve our understanding of the role surface currents play in a large variety of geophysical processes the mission will gather global measurements with high spatial and temporal resolution. A multi-static configuration based on a receive-only C-band dual polarimetric Synthetic Aperture Radar system working in synergy with Sentinel-1 is proposed. The Doppler Centroid Anomaly technique is used in order to measure Total Surface Current Velocity vectors by combining the mono-static observation and the squinted bi-static one. Simultaneous retrieval of Ocean Surface Wind Vectors and Ocean Swell Spectra is also performed. This paper presents an overview of the proposed mission concept and scenario. Some issues specific to multi-static Synthetic Aperture Radar are described and solutions offered. Finally, a preliminary performance assessment of the mission concept is included.
