Abstract

This paper presents the development of a new air coupled ultra wideband (UWB) ground penetrating radar (GPR) for highway pavement and bridge deck inspections. Comparing with many existing highway GPRs of low survey speeds, our system can achieve high spatial resolution and high inspection performance while operating on vehicles driving at regular highway speed. For design validation, steel reinforcing bar detection experiments in different setup conditions are conducted.
