Abstract
The use of differential synthetic aperture radar interferometry (DIFSAR) to analyze the long term effects in volcanic areas was discussed. DIFSAR evaluated the surface deformations by removing from the interferogram, the topographic contribution, computed from an available Digital Elevation Map of the scene under investigation. The ground surface displacements were measured along the line of sight of the radar source. The DIFSAR experiments show that the existence of a long term deformation effect was an actively growing anticline.File in questo prodotto:
