Abstract:The existing horn antennas used in commercial pavement ground penetrating radar (GPR) systems are based on 20-year-old technology and design concepts. In recent years rapid advances have been made in designing planner miniature antennas. In this study a prototype antenna has been designed and tested in the laboratory. The preliminary results indicate that the antenna could transmit and receive GPR energy. In future studies, researchers hope to build a field unit capable of stand-alone operation or a unit that will be mounted on a falling weight deflectometer (FWD) to provide layer thickness information at each test location.
