For through-the-wall-radar signal processing, there exist extensive studies on removing the
wall surface reflection signal, while how to eliminate/alleviate the in-wall structure reflection …

Abstract Ground Penetrating Radar (GPR) is a well-received non-destructive technique for
the detection of underground utilities, such as water/gas pipes, sewers, power cables, and …

We aim to develop a comprehensive tunnel lining detection method and clustering
technique for semi-automatic rebar identification in order to investigate the ten tunnels along …

In this paper, an object characterization method based on neural networks is developed for
GPR subsurface imaging. Currently, most existing studies demonstrate detecting and …

Railroad ballast inspection is critical for the safety of both passenger and freight rail. Ground-
penetrating radar (GPR) has been utilized as a highly efficient nondestructive evaluation …

This thesis focused on classifying GPR cylinders' B-scans according to their depth, size,
material, and the dielectric constant of the underlying medium using four different …

In ground-penetrating radar imaging, the classic back-projection (BP) algorithm has an
excellent reputation for imaging in layered media with convenience and robustness …

A number of physical methods are used to survey railway track ballast to assess its
degradation as a function of deposition. Simulation tests on track models are also …

Ground penetrating radar (GPR) has been shown to be an effective device for detecting
buried objects that have little or no metal content, such as plastic, ceramic, and concrete …
