Title: Satellite-based health monitoring for civil infrastructure
Organisers: Giorgia Giardina (Delft University of Technology), Pietro Milillo (University of Houston, German Aerospace Center (DLR))
In the last decade, the launch of second-generation Synthetic Aperture Radar (SAR) satellites and the parallel evolution of Interferometric SAR (InSAR) processing techniques have made available an unprecedented amount of high-quality measurements of earth surface displacements on large areas. Initially exploited for the evaluation of geophysical phenomena like earthquakes, landslides and volcanos, these measurements are increasingly applied to monitor buildings and infrastructure deformations. With a sensitivity to millimetre displacements, high-spatial density and weekly revisit time, SAR satellites are now a valuable tool in support to structural conditions assessment. This session aims at discussing the most recent challenges and development in InSAR applications to the health monitoring of structures. Topics cover and are not limited to advances in the processing algorithms and application case studies, including tunnels, bridges, dams, pipelines, etc.
