Interferometric investigations with the Sentinel-1 constellation

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
The contribution focuses on the current status of the ESA study entitled “InSARAP Sentinel-1 Constellation Study”, which investigates the interferometric performance of the S1A/S1B units. General aspects like the interferometric compatibility in terms of common range and Doppler bandwidth and the burst synchronization are addressed.

Analysis of Sentinel-1 mission capabilities

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
The Sentinel-1 mission is designed to be a source of continuous and reliable collection of C-band SAR imagery. Requirements for Sentinel-1 end to end system, as part of the complete family of GMES Sentinels, guarantee continuity of C-band SAR data and products availability to operational entities who exploit satellite radar imagery since ERS 1 ...

Grassland monitoring based on Sentinel-1

Remote Sensing for Agriculture, Ecosystems, and Hydrology XXI, 2019
Grassland occupies a large proportion of utilised agricultural area, especially in mountainous regions. Despite its importance current and reliable data on grassland yields and cutting frequencies with a sufficient spatial coverage are lacking. Both are essential for optimizing the use of grassland, nature conservation and policy consultation.

Sentinel-1 SAR system and mission

2017 IEEE Radar Conference (RadarConf), 2017
The paper provides an overview of the Copernicus Sentinel-1 mission, which includes Sentinel-1A (S-1A) and Sentinel-1B (S-1B) satellites, and the characteristics of its SAR system. Sentinel-1 uses pre-programmed SAR mode operations to provide a high revisit frequency and systematic global SAR image coverage.
