Copernicus Sentinel-1 Next Generation Project: Mission and SAR Instrument Performance Analysis in the Phase-0 and A/B1

Abstract:
The Copernicus Sentinel-1 Next Generation (S-1 NG) mission will ensure the continuity of C-band Synthetic Aperture Radar (SAR) data for the next decade, and broaden the spectrum of potential applications and services of the current Sentinel-1 mission by means of advanced capabilities and improved performance. DLR, within the consortium led by TAS-I, has supported both the Phase 0 and the Phase A/B1 of the S-1 NG mission study, funded by the ESA. The activity focused on the definition of the mission concept and of the SAR instrument architecture. A description of the performed analysis and its main outcomes is reported.
