- Abstract
- This paper presents a comprehensive overview of the surface deformation retrieval capability of the Differential
Synthetic Aperture Radar Interferometry (DInSAR) algorithm, referred to as Small BAseline Subset (SBAS)
technique, in the context of active volcanic areas. In particular, after a brief description of the algorithm some
experiments relevant to three selected case-study areas are presented. First, we concentrate on the application of
the SBAS algorithm to a single-orbit scenario, thus considering a set of SAR data composed by images acquired
on descending orbits by the European Remote Sensing (ERS) radar sensors and relevant to the Long Valley
caldera (eastern California) area. Subsequently, we address the capability of the SBAS technique in a multipleorbit
context by referring to Mt. Etna volcano (southern Italy) test site, with respect to which two different ERS
data set, composed by images acquired both on ascending and descending orbits, are available. Finally, we take
advantage of the capability of the algorithm to work in a multi-platform scenario by jointly exploiting two different
sets of SAR images collected by the ERS and the Environment Satellite (ENVISAT) radar sensors in the
Campi Flegrei caldera (southern Italy) area. The presented results demonstrate the effectiveness of the algorithm
to investigate the deformation field in active volcanic areas and the potential of the DInSAR methodologies within
routine surveillance scenario. (literal)
