Sentinel-1 and Sentinel-2 Data Fusion for Urban Change Detection

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
In this paper a new approach based on the fusion of Sentinel-1 and Sentinel-2 products to map urban change detection and to observe suburb's development is presented. The algorithm developed can process data in a fast, automatic and accurate way. To reach this goal, the processing chain uses an iterative multitemporal approach based, for each iteration,

Coupling Sentinel-1 and Sentinel-2 Images for Operational Soil Moisture Mapping

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
The objective of the present paper is to develop an operational approach for soil moisture mapping in agricultural areas at a high spatial resolution over bare soils, as well as soils with vegetation cover. The developed approach is based on the synergic use of radar and optical data and uses the neural network technique to invert the radar signal ...

Assessment of sentinel-1 radiometric stability and quality

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
The main goal of this paper is to assess the radiometric stability of the new Sentinel-1A (S-1A) SAR (Synthetic Aperture Radar) sensors. The S-1A radiometric stability was assessed by analyzing the temporal variations of the backscattering coefficient (σ°) returned from invariant targets. The results show three stable sub-time series of S-1A data.

FDBAQ a novel encoding scheme for Sentinel-1

2009 IEEE International Geoscience and Remote Sensing Symposium, 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

GMES Sentinel-1 mission

Remote Sensing of Environment, 2012
Abstract In the frame of the Global Monitoring for Environment and Security (GMES) Space Component programme, the European Space Agency (ESA) undertook the development of a European Radar Observatory (Sentinel-1), a polar orbiting two-satellite constellation for the continuation and improvement of SAR operational services and applications.

Perspectives of Sentinel - 1 for InSAR applications

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The forthcoming Sentinel-1 will offer high quality, medium resolution interferograms, immediately ready for applications. The reduced revisit interval will lead to many improvements, simplifying the tasks of the researchers. New solutions for the estimate of the NS component of the motion can be considered.
