Ground penetrating radar (GPR) for counter improvised-explosive devices in Thailand

摘要

This paper presents a study on the ground penetrating radar (GPR) for counter improvised-explosive devices in Thailand. In the study, the commercial GPR was used to test a gas tank widely used as a main component of the improvise-explosive device. The test was performed in main two situations that are in an anechoic chamber and on the road. The B-scan images obtained from GPR were analyzed. The recognition technique was developed to detect the improvised-explosive device. The technique is a combination between the regionalization and hyperbolic identification. The results are shown to verify the performance of the proposed technique. Moreover, the A-scan signal at the center of the hyperbolic curve was selected for performing object identification. A short-time matrix pencil method is applied to the system.
