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.

Sentinel-1 Constellation Mission Operations Status

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
As part of the European Copernicus programme, the Sentinel-1 mission, based on a constellation of two SAR satellites, ensures continuity for C-band SAR observations for Europe. Both satellites have been launched from Kourou on a Soyuz rocket, Sentinel-1A on 3rd April 2014, Sentinel-1B on 25 April 2016.

Sentinel-1 high resolution soil moisture

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
The systematic retrieval of near surface soil moisture (SSM) fields at high resolution (e.g., 0.1-1.0 km) is a challenging task that requires the exploitation of new retrieval algorithms and SAR data with advanced observational capabilities (in terms of spatial/temporal resolution, radiometric accuracy, very large swath, long term continuity and rapid ...
