摘要

This paper presents a novel non-contact, nondestructive crack/ defect detection technique using an active millimeter wave radar system operating in V band for automatic structural health monitoring and quality check of consumer products at industry dispatch end. The increasing mishaps due to invisible cracks in building structures, roadways etc has lead to the demand of an accurate, non-destructive forecast system. The designed MMW radar enjoys good cross-range and down-range resolution of 4.27 mm and 8.8 mm, respectively. Further, experimental results show an accurate, non-contact multilayer dielectric thickness measurement as well as concealed crack detection ability of the proposed imaging methodology.
