Abstract

Vapor wake detection is a highly advantageous method and system for detecting explosives and other illicit substances. With vapor wake detection, a canine and a handler are used; however, unlike other detection schemes, the canine leads the handler. After the handler positions the canine in a desired location, the canine detects scents in the air that come to the canine. When the canine detects a trained scent, the canine leads the handler to or follows behind the carrier of the item with the scent. Once the carrier is identified by the handler, the proper personnel are contacted. To implement vapor wake detection effectively, specific rigorous training is utilized.
