Les mesures issues de l'interférométrie d'images radar (InSAR), notamment satellitales, doivent être corrigées du délai dû à la propagation des ondes dans l'atmosphère. Plusieurs travaux ont déjà montré l'intérêt de cette... more
Atmospheric effects are still a limitation to the application of InSAR techniques for displacement measurement. In this study, zenith total delay (ZTD) values derived from global navigation satellite system (GNSS) are used to correct... more
Radar interferometric technology is nowadays considered as one geodetic method to observe earth surface changes. The use of time series analysis in SAR imageries could figure out slow periodical displacement rates on natural hazard... more
Synthetic Aperture Radar (SAR) satellite imagery is a source of data widely employed in the quantification and analysis of an earthquake coseismic displacement. However, due to the signal path along the atmosphere and to other sources,... more
The differential interferometric synthetic aperture radar (DInSAR) method is based on phase variation between the complex value of pixels of timely separated scenes in interferometric SAR pairs. This phase variation has five components:... more
For each pixel, the values of the unwrapped phase produced by interferometric pairs can be parameterized and phase components, such as height, atmospheric path delay difference for the dates of every interferometric set image acquisition,... more
Water vapor is an atmospheric component of major interest in atmospheric science because it affects the energy budget and plays a key role in several atmospheric processes. The Amazonian region is one of the most humid on the planet, and... more

Phase unwrapping is the most informal step of the interferometric SAR processing for calculation of digital elevation model. Present algorithms use two ways for resolving this problem: local and global approach. In this paper we analyze... more
Among other atmospheric regions, ionosphere, which is ionized region of the atmosphere, is considered to impose serious limitations on satellite communication while the effect of other layers, more especially, the troposphere is often... more
As confirmed by many scientists, atmosphere has intensive contaminative role on Interferometric Synthetic Aperture Radar (InSAR) measurements. Atmospheric parameters, always influence radar's phase but the intensity of the... more
India falls under low-latitude region and in this study Ahmedabad region (23.0225° N, 72.5714° E) is considered. In satellite link design system rain plays a crucial part and attenuation caused by rain is severe in Ku and Ka bands. This... more
