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 ...

Sentinel-1 multitemporal SAR products

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
In this paper, we present a new framework for high-level processing of time series images, with particular reference to Sentinel-1 data. The proposed methodology has the goal of enhancing the interpretation of SAR imagery through the production of physical-based RGB composites, which are particularly suited for being easily interpreted by the human ...

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 ...

AGB estimation using Sentinel-2 and Sentinel-1 datasets

Environmental Monitoring and Assessment
Climate change is one of the greatest threats recently, of which developing countries are facing most of the brunt. In the fight against climate change, forests can play an important role, since they hold a substantial amount of terrestrial carbon and can therefore affect the global carbon cycle.

Sentinel-1 mission operations concept

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
In line with the overall Sentinel operations strategy, Sentinel-1, the next European C-Band SAR mission following ERS and ENVISAT, will be operated based on a stable and predefined observation scenario. During the Full Operations Capacity of the mission, this observation scenario will make optimum use of the SAR duty cycle within the technical ...

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.

Mediterranean shrublands biomass estimation using Sentinel-1 and Sentinel-2

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
Potential for synergetic use of Sentinel- 1 and Sentinel-2 for mapping biomass of Mediterranean shrublands is investigated. As preliminary research, backscatter and its ratio from Sentinel-1 (C-band dual polarization SAR), and NDVI from Sentinel-2 (13 bands multi-spectral data) are assessed by using the NDVIR biomass model.

Mountain crop monitoring with multitemporal Sentinel-1 and Sentinel-2 imagery

2017 9th International Workshop on the Analysis of Multitemporal Remote Sensing Images (MultiTemp), 2017
An analysis of radar signal sensitivity to crop and soil conditions was conducted using a time series of Sentinel-1 C-band dual-polarized (VH-VV) SAR images acquired from October 2014 to September 2016 for different crops (meadows, pasture, orchard, vineyards) located in mountain areas.
