| P1-01 | 13:30 | Real-Time Detection of Buried Improvised Explosive Devices through Ground-Penetrating Radar: Implementation and Experimental Analysis Akkarat Boonpoonga (KMUTNB, Thailand) Abstract: A comprehensive approach to the real-time automatic detection of buried Improvised Explosive Devices (IEDs) through the utilization and experimentation of ground-penetrating radar (GPR) technology is presented. The GPR system, encompassing both hardware and software components, was methodically implemented, with a specific focus on the design and integration of an ultra-wideband (UWB) antenna tailored for optimal GPR operation. A series of rigorous experiments were conducted to validate the real-time automatic detection capabilities of the GPR system, leveraging a region-based convolutional neural network (R-CNN) algorithm for IED identification. These experiments involved the deployment of the GPR on both a pickup truck and a maintenance train, each tasked with uncovering buried IEDs beneath roadways and railway tracks, respectively. B-scan images were systematically collected using the implemented GPR system. The detection process entailed a thorough analysis of the hyperbolic patterns within the B-scan images, indicative of buried IEDs. Various preprocessing steps, including zero-offset removal, background removal, and filtering, were applied to enhance the accuracy and reliability of the detection process. The experimental findings clearly demonstrate the effectiveness of the proposed GPR system in outperforming conventional methods reliant on region analysis processing for IED detection. Additionally, the results underscore the importance of preprocessing steps in optimizing the quality of hyperbolic pattern detection. In summary, this study establishes that the GPR system, equipped with an R-CNN algorithm and accompanied by essential preprocessing procedures, offers a robust and real-time solution for the automatic detection of buried IEDs beneath roads and railways, with a specific focus on the identification of hyperbolic patterns within the collected B-scan images. |
