Clay content (fraction < 2 μm) is one of the most important soil properties. It controls soil hydraulic properties like wilting point, field capacity and saturated hydraulic conductivity, which in turn control the various fluxes of water in the unsaturated zone. In our study site, the Kairouan plain in central Tunisia, existing soil maps are neither exhaustive nor sufficiently precise for water...

The SAR (Synthetic Aperture Radar) imagery are largely used for the environmental, structures and infrastructures monitoring. In particular, Differential SAR Interferometry (DInSAR) is a well known technique that allows producing spatially dense displacement maps with centimetre to millimetre accuracy. The SAR signal is characterized by phase and amplitude value and the DInSAR remote sensing te...

Traditionally, Kuand C-band radars are used in ocean scatterometry to retrieve an ocean wind vector. Examples are QuikSCAT and ASCAT satellites. Recently, attempts have been made to use X-band SAR aboard the German TerraSAR-X satellite for the same purpose [1]. Usually, wind retrieval is performed using empirical Geophysical Model Functions (GMF). In the past, a set of GMFs have been designed b...

We combine both amplitude and texture statistics of the Synthetic Aperture Radar (SAR) images for classification purpose. We use Nakagami density to model the class amplitudes and a non-Gaussian Markov Random Field (MRF) texture model with t-distributed regression error to model the textures of the classes. A non-stationary Multinomial Logistic (MnL) latent class label model is used as a mixtur...

This article shows how the array of corner reflectors (CRs) in Queensland, Australia, together with highly accurate geodetic synthetic aperture radar (SAR) techniques-also called imaging geodesy-can be used to measure absolute and relative geometric fidelity SAR missions. We describe, detail, end-to-end methodology apply it TerraSAR-X Stripmap (SM) ScanSAR (SC) data Sentinel-1 interferometric w...

Understanding of exchange processes over Tibetan Plateau including hydrological cycle is becoming increasingly important since their influence on the formation of the Asian monsoon system is known. Recent variation of levels of Tibetan lakes and retreat of mountain glaciers has to be studied in detail with respect to global change. Tibetan Plateau is source area for main Asian rivers that are o...
