Semi-automatic template matching based extraction of hyperbolic signatures in ground-penetrating radar images
Résumé
In civil engineering applications, ground-penetrating radar (GPR) is one of the main non
destructive technique based on the refraction and reflection of electromagnetic waves to probe
the underground and particularly detect damages (cracks, delaminations, texture changes…)
and buried objects (utilities, rebars…). An UWB ground-coupled radar operating in the
frequency band [0.46;4] GHz and made of bowtie slot antennas has been used because,
comparing to a air-launched radar, it increases energy transfer of electromagnetic radiation in
the sub-surface and penetration depth.
