Monitoring Structural Changes and Stability of the Snow Cover with a Ground-Based Synthetic Aperture Radar
The feasibility of retrieving changes in the structure of the snow cover by means of the LISA (LInear SAR) Ground-
Based Synthetic Aperture Radar (GB-SAR) system has been investigated. The LISA instrument consists of a
computer-controlled linear axis 5 m long, a set of transmit and receive antennas, a network analyzer, and a C-Band
amplifier. The system is able to acquire one image every 10 minutes, so it is more suited for studying rapid structural
changes in the snow cover like snow fall or avalanches than the classical satellite imagery. This job presents the first
ground-based radar images of natural and artificially triggered avalanches as well as of snow fall in the Swiss Alps,
confirming the potential use of GB-SAR for the monitoring of the snow cover.
