WaveDINO: Learning-Based Atmospheric Correction of Unwrapped InSAR Interferograms Validated by GNSS: Results at Laguna del Maule and Campi Flegrei Volcanoes
Robert Popescu, Juliet Biggs, Tianyuan Zhu +1
Interferometric Synthetic Aperture Radar (InSAR) enables effective monitoring of volcanic deformation; however, the observed signals are often corrupted by atmospheric phase delays…
An InSAR Phase Unwrapping Framework for Large-scale and Complex Events
Yijia Song, Juliet Biggs, Alin Achim +3
Phase unwrapping remains a critical and challenging problem in InSAR processing, particularly in scenarios involving complex deformation patterns. In earthquake-related deformation…
UnwrapDiff: A Conditional Diffusion Model for InSAR Phase Unwrapping
Yijia Song, Juliet Biggs, Alin Achim +3
Phase unwrapping is a fundamental problem in InSAR data processing, supporting geophysical applications such as deformation monitoring and hazard assessment. Its reliability is lim…
Anomaly detection for the identification of volcanic unrest in satellite imagery
Robert Gabriel Popescu, Nantheera Anantrasirichai, Juliet Biggs
Satellite images have the potential to detect volcanic deformation prior to eruptions, but while a vast number of images are routinely acquired, only a small percentage contain vol…
