Article Title: Identification of Pipelines from the Secondary Reflect Wave Travel Time of Ground-Penetrating Radar Waves
by Kun. Fa. Lee

Abstract:
When using ground-penetrating radar to identify underground pipelines of similar dielectric constants (i.e. PE and PVC), misidentification of different pipelines is quite likely. In this study, by considering secondary-reflected travel-times theory of radar waves, we calculated dielectric constants of pipelines for which PE- and PVC-type non-metal pipelines were identified. An experiment by placing PE- and PVC-type non-metal pipelines and heavy metal (iron) pipelines in water were conducted. Based on the travel-time calculation, the dielectric constants of non-metal pipelines of similar composition (PE: 2.3 and PVC: 3.0) were quite close. The differences between experimental and theoretical values are acceptable in construction work and U.S.A.ASTMD4748-98 standard error range on +_ 0.2 in (0.508cm) completely Less than, it is qualified. As a result, not only can this study be used to detect metal pipelines, it can also be used to differentiate between non-metal pipelines submerged in water.
