—Tropospheric inhomogeneities can form a major error source in differential synthetic aperture radar interferom-etry measurements, which are used in slow-deformation monitoring. Indeed, variations of atmospheric conditions between two radar acquisitions produce variations in the signal path of two images and, thus, additional fringes on differential(More)
Nine ERS-1 and ERS-2 descending orbit data acquired over the Aira Caldera between June 1995 and November 1998 were used to create 31 differential interferograms. Although the interferograms exhibit a relatively low level of coherence, even for couples sampling short time intervals (6 months), Differential Interferometric Synthetic Aperture 5 Radar (DinSAR)(More)
Using combinations of adequately selected ERS-2 SAR images, the co-seismic deformation field associated with the Athens earthquake was analyzed. The observed fringes indicate a minimum of 56mm change in slant range direction. To assess the location and geometry of the seismic fault and the amplitude of the slip, a simple dislocation model in elastic(More)

— The presence of atmospheric contributions in SAR interferograms represents the main limit for the detection of ground deformation movements. This paper presents a method-ological approach to reduce at both global and local scales the tropospheric contributions in the interferograms. It first requires the refined knowledge of the permanent scatterers that(More)
Remerciements Au terme de ce travail de thèse, je tiens, tout d'abord, à remercier Michel Kasser de m'avoir proposé ce sujet de thèse, de son professionnalisme, sa confiance et ses encouragements qui m'ont donné envie d'aller jusqu'au bout, et qui a essayé d'être toujours disponible malgré un emploi de temps très chargé. Je remercie très chaleureusement les(More)
