Paper Abstract

Within the European Commission’s Seventh Framework Programme (FP7), the CONSORTIS project will design and fabricate a stand-off system for the detection of objects concealed on people. This system operating in the sub-millimetre wave part of the spectrum will scan people as they walk by the sensor. The aim of the project is to produce a system which has a high probability of detection, low false alarm rates, is non-invasive and respects privacy. The top level system design for CONSORTIS brings together both passive and active sensors and the simulation tools developed to evaluate the design are described. The passive system will operate in two or three bands between 100 and 600GHz and will be based on a cryogen free cooled focal plane array sensor whilst the active system will be a solid-state 340GHz radar. This will maximize the probability of detection and reduce false alarms. A ‘systems engineering’ approach was adopted with performance modeling being used to develop the system specifications. A modified version of OpenFx is used to model the passive system and SE-RAY-EM for the active system. Both of these tools are capable of rendering imagery which is electromagnetically correct and account for the properties of the sensor. Furthermore this imagery can be animated to give moving images similar to those observed in the real system. Targets can be embedded under clothing so that performance can be estimated. False alarms can be introduced in a similar way to understand if their signatures can be rejected.
