| Description: | Technical Report Abstract: This project was a cooperative effort between the U.S. Army Engineer Waterways Experiment Station (WES) and the University of Illinois under a Cooperative Research and Development Agreement as part of the Construction Productivity Advancement Research Program. The purpose was to develop a portable radar system for nondestructive evaluation (NDE) of concrete. Two approaches, a time-domain pulse system and a frequency-domain system, were investigated. An ultra-wideband (UWB) time-domain pulse radar NDE system was developed at the University of Illinois and field tested at WES. The UWB time-domain impulse radar system successfully demonstrated the capability of detecting small reinforcement bars embedded in large concrete blocks. This report describes the development of the UWB time-domain NDE system in detail and illustrates several experimental results. |
