Advanced Phase Unwrapping Techniques in InSAR
Webinar Speaker: Prof. Hanwen Yu, School of Resources and Environment, University of Electronic Science and Technology of China
About the Webinar
2D phase unwrapping (PU) is one of the biggest challenges in synthetic aperture radar (SAR) interferometry (InSAR) processing. As an ill-posed problem, the performance of the traditional algorithmic model-based 2D PU algorithms is not guaranteed to be correct with rapid ground deformation or topographic changes. This presentation will introduce two advanced PU techniques (TSPA technique and deep-learning based PU techniques), which break up the limits of the phase continuity assumption and to enhance the 2D PU solutions in the previously theoretically and practically infeasible scenarios.
Hanwen Yu (Senior Menber, IEEE) received the B.S. and Ph.D. degrees in electronic engineering from the Xidian University, Xian, in 2007 and 2012, respectively. He was a Post-Doctoral Research Fellow with the Department of Civil and Environmental Engineering, National Center for Airborne Laser Mapping, University of Houston, Houston, TX, USA. Currently, he is a full-professor at the School of Resources and Environment in University of Electronic Science and Technology of China, Chengdu, China, and is an adjunct professor at the Ph.D. School in Information and Communication Technology and Engineering in University of Napoli Parthenope, Napoli, Italy. He has authored or coauthored more than 40 research articles in high-impact peer-reviewed journals, such as the IEEE Transactions on Geoscience and Remote Sensing, the IEEE Transactions on Image Processing, and Remote Sensing of Environment. His research interests include phase unwrapping, machine learning, and synthetic aperture radar (SAR) interferometry (InSAR) signal processing and applications. Prof. Yu has reviewed more than 260 manuscripts for over 20 different journals. He was a recipient of the Recognition of Best Reviewer of the IEEE Transactions on Geoscience and Remote Sensing in 2019. Prof. Yu serves as a Topical Associate Editor in the IEEE Transactions on Geoscience and Remote Sensing, and an Associate Editor in the IEEE Geoscience and Remote Sensing Magazine. He has guest edited 5 special issues on InSAR remote sensing for different journals (e.g., IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing and MDPI Remote Sensing).
