Establishment of Integrated Model for Explosive Detection

Abstract

Terror threat to civilization has been increasing all over the world. Thus it is important to detect explosive objects in gathering place, in order to assure safety and security. However sufficient explosive-detection system has not existed. Part of the reason for this fact is the limitation of detection accuracy using only one detector. From a practical point of view, we also detect explosives not to prevent the flow of people. In order to accomplish these two objectives, we propose integrated model for explosive detection. Using this model, we could achieve high detection accuracy without preventing the flow of crowd. We examined three detectors as a case study: millimeter-wave imaging detector, VUV-SPI-TOFMS detector, and pulsed neutron detector. We have established the integrated model using these detectors, and assured the improvement of detection accuracy.
