GMES Sentinel-1 mission
Ramon Torres,Paul Snoeij,Dirk Geudtner,David Bibby,Malcolm Davidson,Evert Attema,Pierre Potin,Bjorn Rommen,Nicolas Floury,Michael Brown,Ignacio Navas Traver,Patrick Deghaye,Berthyl Duesmann,Betlem Rosich,Nuno Miranda,Claudio Bruno,Michelangelo L'Abbate,Renato Croci,Andrea Pietropaolo,Markus Huchler,Friedhelm Rostan +20 more
TL;DR: The unique data availability performance of the Sentinel-1 routine operations makes the mission particularly suitable for emergency response support, marine surveillance, ice monitoring and interferometric applications such as detection of subsidence and landslides.
Journal ArticleDOI
Joint statistical properties of RMS height and correlation length derived from multisite 1-m roughness measurements
Malcolm Davidson,F. Mattia,Giuseppe Satalino,Niko E. C. Verhoest,T. Le Toan,M. Borgeaud,J. Louis,Evert Attema +7 more
TL;DR: A unique pan-European database of profile measurements covering five different sites and containing approximately 1.5 km of profile data is used to establish the joint roughness statistics for rms height s and correlation length l for agricultural bare soil fields and a variety of tillage conditions.
Journal ArticleDOI
Flexible Dynamic Block Adaptive Quantization for Sentinel-1 SAR Missions
Evert Attema,C. Cafforio,M Gottwald,Pietro Guccione,A. Monti Guarnieri,Fabio Rocca,Paul Snoeij +6 more
TL;DR: The letter introduces a novel quantizer suited for medium to high-resolution synthetic aperture radar (SAR) systems, like the forthcoming SENTINEL-1 SAR, by adaptively tuning the quantizer rate according to the local signal-to-noise-ratio (SNR).
Sentinel-1 - the radar mission for GMES operational land and sea services
Evert Attema,Pierre Bargellini,Peter Edwards,Guido Levrini,Svein Lokas,Ludwig Moeller,Betlem Rosich-Tell,Patrizia Secchi,Ramon Torres,Malcolm Davidson,Paul Snoeij +10 more
TL;DR: The European Union-ESA Global Monitoring for Environment and Security (GMES) project as discussed by the authors developed the Sentinel-1 Euro-pean Radar Observatory, a polar-orbiting satellite for operational SAR applications.
Journal ArticleDOI
