Abstract :
In this laboratory study, the comparison of 4 different antenna frequencies (from 1.0 to 2.6 GHz) and radar systems on the same masonry and post-tensioned concrete specimens has served to investigate the precision achievable in imaging cross sections of masonry walls with different brick layouts and of concrete slabs with metal post-tensioning ducts at varying depths. Through high-density 3D data collection and multi-phase post-processing, the work aimed at 2D and 3D data imaging for eased and enhanced diagnosis of structural elements.
