Abstract:

Interferometric synthetic aperture radar (InSAR) can be used to measure ground displacement over large geographic areas. However, while detecting deformation using InSAR images is conceptually straightforward, it is difficult to automate, particularly in volcanic regions as atmospheric water vapor is a particular challenge.



In this talk, a simple but efficient deep learning framework to detect ground deformation will be present. The model can be applied to individual interferograms for rapid deformations and can be tested on time-series for slow and sustained ones. The image processing techniques employed in the framework will also be discussed. Finally, the current detection results on global Sentinel data processed via LiCSAR system will be shown.
