C-band SAR for the GMES Sentinel-1 mission

The EU-ESA Global Monitoring for Environment and Security (GMES) program calls for a number of different Satellites called Sentinels to be launched within the next 6 years. The first among these are the two Sentinel-1 polar orbiting sun-synchronous satellites which each carries onboard a C-band Synthetic Aperture Radar (C-SAR).
