Optimisation et augmentation d'une chaîne de traitement InSAR

Abstract : Within the framework of monitoring projects, Fugro is in charge of field surveying in areas affected by subsidence of anthropogenic and natural origins. Since many years and for this purpose Fugro has been developing GEOMON, a solution which would allow the combination of geodetic measurements (InSAR, GNSS, levelling, precision LiDAR and Tilt meters). An optimization of the entire InSAR streamline from the downloading of SAR images to the achievement of the results has been carried out, and two new plug-ins that can be used under QGIS have been developed. We have also tried to mitigate the impact of tropospheric delays on the interferograms, for this aim, the Toolbox TRAIN has been used to apply atmospheric corrections. Addingly, we simulated a deformation model (subsidence) by a mathematically known form, which we then tried to recreate from a new radial interpolation technique, that was validated in the light of the results obtained and which offers a good alternative to the regression kriging used by the GEOMON solution.
