Concept for an Entry Control Facility (ECF) Featuring Hazardous Substances Detection Capabilities as an Element for Military Camp Protection

Asymmetric threats require powerful surveillance technology which helps to preserve the security. Security checks which focus on Improvised Explosive Devices (IED’s) or the identification of persons carrying hazardous substances are the major task of our research within the HAMLeT+ (Hazardous Material Localization and Person Tracking) project. Further on, there is a pressing need for assisting the security personnel, either civil or military, by extending the detection capabilities and to deliver efficient and reliable, real time decision support for their task to percept threats. Military camp protection with heterogeneous net-worked sensors and comprehensive sensor data fusion could be such an element. The technology developments concentrate on the integration of different sensor types (video, tracking sensors, CBRNE sensors) in order to get a better and comprehensive understanding in a defined entry area. Data fusion is used to combine kinematic data of persons (where, when) with additional attribute information of them (what) in order to identify that single person carrying the attributes and to classify the threat. The project was initiated as a Supporting Activity funded by the EU within the PASR 2006 scheme. With regards to the specific task for military camp protection it was extended and redesigned. In HAMLeT+ several chemical sensors for hydrocarbons like fuels, alcohols or solvents were used. Such chemicals are available in bigger amounts on the free market. Using them e.g. as fire accelerants they can cause a huge damage. Therefore their detection or the detection of persons carrying such substances or having contaminations on their clothes is of great interest. Sensitive devices for the detection of these analytes are e.g. metal oxide sensors [1]. Our presentation illustrates experimental data, which were gathered with the experimental system HAMLeT+ during the NATO “Defense Against Terrorism (DAT)” campaign „COMMON SHIELDS” in August and September 2008
