Abstract
Ultrawideband noise signals have shown proven benefits in the realm of remote sensing for decades--aiding in the detection and localization of potentially harmful concealed objects. The characteristics of these waveforms show promise in the area of nondestructive testing for the detection of defects within multilayered structures. In this paper, we develop an approach to identify noise waveforms that will perform as effectively, or outperform, other common waveforms used in microwave imaging. Experimental data are gathered using a microwave imaging system operating in the X-band frequency range to detect the presence of water in dielectric materials and air voids in concrete walls reinforced with glass-fiber reinforced polymers.
