Abstract
A detection system and methods are described for determining whether a target contains a selected substance or device such as an explosive device, illegal drugs, dangerous chemicals, or the like. According to some embodiments, a detection system is comprising a radiation source and one or more detectors. The detection system in this directs radiation from a distance and towards a target suspected to contain a dangerous device or substance. A response is detected from the target. The response is compared to one or more templates that represent known explosives, drugs, dangerous chemicals, or the like. A score may be generated that corresponds to a similarity between the targeted and known substances. When the score indicates that the target substance is likely to be dangerous or contraband, then an alarm or other indication may be generated in some embodiments.
