|Abstract(s):||Non-destructive investigation using Ground Penetrating Radar is becoming more popular during the inspection of civil structures. Currently, traditional 2D imaging is also used as a preliminary tool to find possible areas of interest for more detailed inspection, which can be accomplished by 3D image reconstruction or tomography techniques. In this paper, a general overview of the work done at University of Minho regarding these techniques is presented. Data acquisition was performed on two masonry walls and on one large concrete specimen. In case of masonry specimens traditional 2D imaging was supplemented by the use of transmission tomography. Data acquisition on the concrete specimen was done in reflection mode and results were further processed using 3D reconstruction software. Results from these specimens are very promising. Radar tomography and 3D image reconstruction techniques provided much more detailed information about structural integrity and shapes and location of the voids placed inside the tested specimens relatively to 2D imaging originally used for potential target identification.|
