Abstract

The use of scattered radiation in the production of signatures for explosive detection has been studied. Signatures have been measured and the spectral analysis of these using multivariate statistics has demonstrated that explosives within realistic environments can be recognized. The problem remains of how to use this information in the time frame allowed by airport baggage security checks. To address these problems we have developed a 'tuned' system approach. The energy-angle space diagrams have been created and the areas containing the greatest information density in the presence of an explosive have been identified. A specially designed detector (CdZnTe) array has been built to match these regions. The array has been used to identify explosives hidden within realistic case situations.
