Geophysical and Environmental Applications of Imaging Radar Systems
Radar imaging is a powerful technique in Earth Observation (EO) and remote sensing that can provide novel insights into the physical processes that shape and govern the Earth system. Synthetic Aperture Radar (SAR) is an active source microwave imaging technique that exploits the relative motion of the instrument platform – including satellites, aircraft, and drones – to generate a synthetic long aperture phased array, which enables coherent phase and backscatter imaging at fine (~1-10 m) spatial resolution. SAR enables detailed, non-invasive mapping and exploration of surface and near-subsurface features, with applications in geological hazard mitigation, environmental resource management, land surface dynamics, hydrology, and geospatial intelligence collection. In this seminar, I will provide a brief overview and introduction to the field of SAR and Interferometric Synthetic Aperture Radar (InSAR), with an emphasis on applications in the realm of environmental geophysics. I will also discuss emerging trends in InSAR time series analysis, error and uncertainty quantification, SAR focusing algorithms.
