This paper presents an original methodology to retrieve surface soil moisture based on the use of the ENVISAT-ASAR multi-incidence angle sensor. Previous studies using ERS and RADARSAT SAR have shown the potential of radar signals to monitor surface soil moisture with one incidence-angle data and a simple linear relationship. This work aims at developing(More)

We study the capabilities of low frequency radar systems to sound the subsurface in arid countries. This approach is based on the coupling between two complementary radar techniques: the airborne Synthetic Aperture Radar (SAR) used in L-band (1.2 GHz) for imaging large scale subsurface structures, and the Ground-Penetrating Radar (GPR) used between 500 and(More)
The objective of this paper is to improve the understanding of surface roughness description based on experimental campaigns involving the ASAR-ENVISAT (Advanced Synthetic Aperture Radar) radar. Two presentations of surface correlation function are proposed in this study: () () () α ρ l x e s x / 2 − = and () () [ ] ()) / (2 / l x b a a l x e s x + − = ρ.(More)
