A Weak-Signal-Aware Framework for Subsurface Defect Detection: Mechanisms for Enhancing Low-SCR Hyperbolic Signatures
arXiv:2604.05490v1 Announce Type: new
Abstract: Subsurface defect detection via Ground Penetrating Radar is challenged by “weak signals” faint diffraction hyperbolas with low signal-to-clutter ratios, high wavefield similarity, and geometric degradati…
