Tadar security system

The Irish company Farran Technology has developed a new security imaging system that can ‘see’ all concealed objects on a person, not just metallic objects by the use of a millimetre-wave camera. The technology originates from microwave and millimetre-wave systems supplied to ESA. The Tadar system can work in passive and active mode. In passive mode the person to be screened must stand in front of the system, while in active mode the system can produce three-dimensional images of a scene, even at a distance of over 50 metres.
