Abstract

A millimetre wave (75 - 110 GHz) polarimetric RADAR system is demonstrated for the detection of threat objects concealed under clothing upon the human body at stand-off ranges of up to 25 metres. The system implements Swept Frequency Continuous Wave RADAR with low cost components to deliver a compact, UWB, high resolution (~ 1 cm) RADAR system capable of detecting, resolving and discriminating a wide spectrum of threat items concealed on the human body. Threat detection is autonomously rendered by application of a neural network to the scattered time domain polarimetric radar return, the system may be taught to alarm or reject certain classes of objects; allowing for highly specific through to broad spectrum threat detection. The authors present data for some simple envisaged threat scenarios at stand off ranges out to 25 metres.
