Abstract

Within the European Commission Seventh Framework Programme (FP7), CONSORTIS (Concealed Object Stand-Off
Real-Time Imaging for Security) has designed and is fabricating a stand-off system operating at sub-millimetre wave
frequencies for the detection of objects concealed on people. This system scans people as they walk by the sensor.
This paper presents the top level system design which brings together both passive and active sensors to provide good
performance. The passive system operates in two bands between 100 and 600GHz and is based on a cryogen free cooled
focal plane array sensor whilst the active system is a solid-state 340GHz radar.
A modified version of OpenFX was used for modeling the passive system. This model was recently modified to include
realistic location-specific skin temperature and to accept animated characters wearing up to three layers of clothing that
move dynamically, such as those typically found in cinematography. Targets under clothing have been modeled and the
performance simulated. The strengths and weaknesses of this modelling approach are discussed.
