ABSTRACT
The article describes a new sensor that will be used by British security forces to detect concealed weapons at airports or railways. The Tadar sensing system is designed to detect metallic and non-metallic objects by measuring a person's radiated body heat by scanning them against a temperature-controlled background panel. The presence of an object between the clothes and the body blocks the body's natural energy and the thermal contrast provides an image of the object.
