Surface Penetrating Radar and Other Non-Destructive Testing Methods


I have been working on the development of intelligent surface-penetrating radar systems. This research is highly interdisciplinary, drawing upon knowledge from advanced antenna systems, radar technologies, and artificial intelligence. My contributions include the design of ultra-wideband multi-polarimetric GPR antennas, the advancement of measurement techniques, and the development of deep learning augmented data processing and interpretation algorithms. As a pioneering attempt, we have combined powerful capabilities of deep learning algorithms with GPR domain knowledge and engineered several neural network architectures in completing challenging GPR tasks, including clutter removal in radargrams, object parameter estimation, and underground scenario mapping. All of my work on GPR can be found on this page.
