Résumé

Interferometric Synthetic Aperture Radar (InSAR) measurements are often biased due to atmospheric effects. Especially, the tropospheric water vapor engenders a delay of SAR signal propagation. In this paper, we propose a specific methodology for atmospheric effects correction on SAR interferograms. It is based on ancillary data collected from NOAA-AVHRR sensor. The specificity of the approach consists in its applicability where no ground truth GPS measurements are available neither for calibration nor for result validation. An adaptive validation demarche is also proposed.
