This study demonstrates precision non-destructive inspection of periodic linear targets using polarimetry technique used in radars with frequency bands from P to W (0.3 to 110 GHz) and broadband terahertz pulse. The polarimetry technique is effective to identify targets in radar field, and terahertz waves are effective for non-destructive inspection due to its broadband and special penetration characteristics. In this study, we combine the both techniques to enhance the inspection accuracy. Our analytical and experimental results confirmed that the combination of the polarimetry technique and the broadband terahertz pulse wave was effective for the precision inspection of the targets.
