Paper Abstract

Ground Penetrating Radar (GPR) is increasingly used for non- destructive investigations of concrete structures in civil engineering. The success of any radar investigation depends on the duration of the radiated radar impulse and on the radiation pattern of the antenna. These antenna characteristics influence the spatial resolution of the radar image. To increase the spatial resolution, a high frequency antenna was developed. For this new antenna and two commercial antennas both mentioned antenna characteristics were determined using a concrete half sphere. The different performance of these antennas due to the different characteristics is demonstrated by comparison measurements at two concrete specimens.
