The main goal of this course is to provide students with the background needed to use SAR and InSAR data as a source of geodetic information. The course starts with an introduction to passive and active microwave remote sensing and a discussion of methods of Synthetic Aperture Radar (SAR) processing. It then presents an in-depth description of methods and applications of InSAR, including traditional InSAR methods and advanced InSAR Time Series analysis techniques. A thorough description of the main limitations and error sources of these techniques is included to allow for the retrieval of geodetic information from SAR and InSAR observations. It will be shown that SAR and InSAR data can be used to provide geodetic observations of geodynamic and anthropogenic processes of the earth’s surface and interior with high accuracy and resolution. It will also be shown that SAR data can provide high resolution observations of atmospheric and ionospheric constituents. In conclusion, methods for the integration of geodetic observations from SAR with geophysical models and observations from other sensors will be presented.
