摘要：

An imaging scheme has been developed and proposed for the use of radar in detecting steel. reinforcing bars embedded inside concrete. The scheme utilizes the measured data of electromagnetic properties of concrete and impedance mismatch between concrete and the steel bar. In the paper, the electromagnetic properties of concrete measured over a frequency range from 1 to 6 GHz are also presented. The results provided a ground work in improving imagery from radar measurements for nondestructive testing of concrete structures.
