Abstract
In this work the potentiality of multi-source and multifrequency Synthetic Aperture Radar (SAR) images to measure surface deformation of the Lazaun alpine active rock glacier were studied. CSG, CSK, TerraSAR-X, Sentinel-1 and SAOCOM SAR data characterized by different wavelength and spatial and temporal resolutions have been tested over the period 2016 to 2022. Intensity tracking and DInSAR complementary SAR techniques have been used to estimate deformation at different temporal scales. We found for Intensity tracking, interannual displacement reaching a Pearson correlation coefficient of about 0.89 and an RMSE of 0.34mm/day.
