- Abstract
The monitoring of concrete structures is of great importance for preventing people injury and collapses. In this respect, Ground Penetrating Radar (GPR) systems can be seen as valuable tools in the non-destructive diagnostic process. However, the interpretation of raw radar data is sometimes very difficult, and therefore suitable reconstruction procedures are needed to properly investigate the presence of internal voids, cracks, defects or metallic rebars. Although a significant number of qualitative and quantitative imaging methods have been proposed in the scientific literature, further investigations are still needed in order to overcome the limitations of currently available techniques and to further improve the attainable results [1]. In this framework, the purpose of this work is to assess and compare the imaging capabilities of some specific GPR imaging techniques in the presence of realistic concrete structures, accurately simulated with a time-domain electromagnetic solver [2].[1] I.
