Dr. Hai-Hun Sun of University of Wisconsin-Madison

Under the surface lies a world of mysteries that has fascinated mankind for centuries.Ground-Penetrating Radar (GPR), employing electromagnetic waves for non-destructive probing of the subsurface world, has become a pivotal tool in this intriguing pursuit. Since its inception a century ago, its applications have continuously expanded to encompass fields such as civil and environmental engineering,geophysics, archaeology, and even space exploration! In this talk, The author will provide a brief introduction to the history and operating principles of GPR systems and will present the latest advancements in their antennas and data processing techniques. A significant focus will be on their pioneering efforts to integrate GPR domain knowledge with artificial intelligence (AI) in order to enhance the interpretability of GPR signals and to address the many challenging tasks faced in their real-world applications. These tasks include, but are not limited to, removing clutter in radargrams, estimating key parameters of subsurface objects, and mapping subsurface permittivity distributions with high resolution. This talk aims to provide a fresh perspective on GPR technology and its potential to significantly advance our understanding of the fascinating subsurface world.
