Highlights

  • Ground Penetrating Radar (GPR) for Non-Destructive Testing (NDT) has been successfully introduced in a wide range of sectors, such as mining and geology, glaciology, civil engineering and civil works, archaeology, and security and defense

  • This Special Issue comprises a set of contributions covering both hardware and software improvements for enhanced GPR imaging

  • DLGPR systems provide good dynamic range thanks to the short distance between the radar and the ground, but at the expense of strong clutter coming from the air-ground interface

Summary

Introduction

Ground Penetrating Radar (GPR) has become one of the key technologies in subsurface sensing and, in general, in Non-Destructive Testing (NDT), since it is able to detect both metallic and nonmetallic targets It can provide images from the underground, improving detection capabilities. Novel and robust algorithms have been developed for noise and clutter reduction, automatic target recognition, and efficient processing of large sets of measurements to enable real-time imaging, among others. This Special Issue comprises a set of contributions covering both hardware and software improvements for enhanced GPR imaging.
