Sentinel-1 CSAR mission status

SPIE Proceedings, 2009
The Sentinel-1 synthetic aperture radar (SAR) constellation represents a completely new approach to SAR mission design by ESA in direct response to the operational needs for SAR data expressed under the EU-ESA Global Monitoring for Environment and Security (GMES) programme. The Sentinel-1 constellation is expected to provide near daily coverage over

Sentinel-1 System capabilities and applications

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
The paper provides an overview of the Copernicus Sentinel-1 system capabilities and applications. In particular, the characteristics of the Sentinel-1 SAR imaging modes and their key performance parameters are described. In addition, the Sentinel-1 SAR interferometry (InSAR) capabilities, especially for TOPS InSAR and the strategy for maintaining the ...

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.

GMES Sentinel-1 FDBAQ performance analysis

2009 IEEE Radar Conference, 2009
Modern operational and/or high resolution SAR satellite missions impose stringent requirements on on-board data compression such as a higher data reduction ratio, more flexibility, and faster data throughput. A novel approach is Flexible Dynamic Block Adaptive Quantization (FDBAQ). This method outperforms currently used Block Adaptive Quantization with

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 ...

Status and Evolution of the Sentinel-1 Mission

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
The routine operations of the Copernicus Sentinel-1 mission constellation are on-going and performed at full mission capacity. The C-band SAR mission is characterized by large-scale and repetitive observations, systematic production and free and open data policy. Sentinel-1 data are routinely used by Copernicus and many operational services, and in the

Prospects of Sentinel-1 for land applications

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The Sentinel-1 mission is a polar-orbiting satellite constellation for the continuation of C-band Synthetic Aperture Radar (SAR) applications. Contrary to its predecessor instruments onboard of ENVISAT and RADARSAT, the Sentinel-1 satellites will be operated following a predefined and fixed baseline acquisition scenario.

Irrigation Mapping Using Sentinel-1 Time Series

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
The obj ective of this paper is to present an approach for mapping irrigated areas at plot scale using the Sentinel-1 radar time series. Over a study site located in Catalonia region of north Spain, a dense temporal series of S1 backscattering coefficients were first obtained at plot scale and grid scale (10km x 10km).
