TOPIC
Phase unwrapping is the cornerstone of many interferometric techniques, including Interferometric Synthetic Aperture Radar (InSAR) and Distributed Acoustic Sensing (DAS). Yet its quantitative accuracy is usually verified with external reference data, leaving these methods unable to self-validate their products. This talk introduces, under a no-external-data assumption, a necessary condition for quantitatively evaluating the accuracy of single-baseline (ill-posed) phase unwrapping and a necessary-and-sufficient condition for quantitatively evaluating the accuracy of multi-baseline (well-posed) phase unwrapping.
ABOUT THE LECTURER

Hanwen Yu is an IEEE Fellow and a professor in the School of Resources and Environment at the University of Electronic Science and Technology of China (UESTC). He was selected for China’s national‐level talent program and also holds adjunct professorships at the University of Naples “Federico II” in Italy and at Xidian University.
The TSPA-InSAR method he proposed earned the IEEE GRSS Transactions Prize Paper Award in 2021 (the sole awardee worldwide that year) and Huawei’s Spark Award in 2023, and it has been continuously supported by the Huawei Talent Fund.
Prof. Yu currently serves on the Administrative Committee of the IEEE Geoscience and Remote Sensing Society (GRSS). He is the first Chinese Editor-in-Chief of the IEEE Journal on Miniaturization for Air and Space Systems and an Associate Editor for both IEEE Geoscience and Remote Sensing Magazine (a top CAS Zone 1 journal, IF 16.2) and IEEE Transactions on Geoscience and Remote Sensing (a top CAS Zone 1 journal, IF 7.5).
