Ground-Based SAR for deformation monitoring: data analysis

Ground-based Synthetic Aperture Radar (GBSAR) is a powerful terrestrial radar-based technique able to measure and monitor surface deformation. The GBSAR has been used in the last years in a variety of application fields including the monitoring of landslides, rock falls, subsidence phenomena, mining sites, etc. The increasing interest in this technique has lead a wide range of technicians, young researchers, scientists and managers from different disciplines to process and analyse this innovative kind of data. The course is addressed to all of them, covering the relevant aspects of GBSAR data analysis to understand advantages and limitations of this new technique and to correctly exploit and interpret its data. The main components of the GBSAR chain, including the design of the campaign, data acquisition, screening, processing, analysis, geocoding and visualization, will be discussed during the course. An introduction to the fundamentals of terrestrial SAR and deformation measurement by SAR interferometry will be provided, followed by an in-depth discussion of different types of deformation monitoring approaches, emphasizing the practical aspects and analyzing different types of deformation phenomena and monitoring scenarios. Lectures will be complemented by hands-on sessions where practical exercises, using actual GBSAR data and the experimental in-house developed software of the Geomatics Division of CTTC, will be carried out.
