Education & Training: Detection and Monitoring of ground movement using InSAR (Interferometric Synthetic Aperture Radar)

Cutting-edge SAR satellites are capable of identifying millimetric ground motion. They can therefore provide information that is highly relevant for the design and monitoring of buildings and infrastructures. The detection of minimal displacements that precede landslides (pre-failure deformation) represents another increasingly important field of InSAR application.

 

Since 2014 the Copernicus Earth observation program (EU, ESA) provides Sentinel-1 radar data with (nearly) worldwide coverage at no costs. Currently there is almost a dozen of SAR satellites – a number that is set to increase rapidly in the near future. InSAR data will thus soon be readily available in even higher temporal and spatial resolutions. Already, ground movement rates derived from InSAR data have been made freely accessible for specific regions (e.g. for the province of Salzburg, refer to Weblink). Based on a more frequent data collection and improved data analysis procedures the significance of InSAR derivates will continue to grow for the foreseeable future.

 

The interpretation of InSAR data requires sound, fundamental knowledge on the operating principle of radar satellites and the basics of data processing. In addition, physical conditions and infrastructural properties need to be carefully considered for a successful interpretation.

 

Our InSAR training provides an overview of the necessary basic knowledge and the current state of the art, and gives you a practice-oriented introduction to the world of InSAR. In two concise modules we (i) will help you to get familiar with the technical basics of satellite-based InSAR in a comprehensible way, and (ii) give a hands-on introduction to the evaluation and further use/processing of the discussed InSAR data. Participants based in Austria can use the FFG Digital Skills Check to get up to 80 % of the course fees refunded. For further information on our trainings, please refer to our InSAR specialist Markus Dörfler (markus.doerfler@georesearch.ac.at).
