Open Area Concealed Weapon Detection Sensor System Development

An open area concealed weapon detection (CWD) system to identify potential threat and non-threat targets on the basis of the induced electromagnetic signature is presented. The signature identifies the material, size and shape of different weapons enabling other metallic objects that pose no threat to be filtered out. Moreover, the signal analysis and database system is established to process the acquired object information and categorize them according to the different features of a concealed weapon. The method analyzes the time-domain difference between the received object data and the background which then identifies the individual response of potential weapons. The proposed method experimentally shows the innovation to classify the different dangerous targets in the open area based on the material, size, shape and location in realtime.
