The overall objective:

To develop and pilot a dual-mode (active/passive multiband) submillimetre wave (SMMW) video-rate people-screening imaging system with automated anomaly detection capability for reliable, discreet and rapid threat object detection.

This system will have the following properties:

  • Non-intrusive, safe and accurate – SMMW systems are non-ionizing, and the exposure level for the active front end illumination will be well below the established limit.
  • Speed –the system will be capable of near-real time imaging to facilitate “walk-by” security screening solutions.
  • SMMW (“THz”) operation – the system will incorporate passive sensors covering frequencies from ~200 to ~600 GHz, and the active radar also operates in this band.
  • Multi-frequency operation – the passive system will cover more than one frequency band for differentiation of materials.
  • Automated threat recognition capability - Algorithms will be developed to make use of the complementary image outputs of the passive and active sensors.
  • Privacy issues – strong involvement of ethics experts minimises the potential issue with privacy.
  • Pilot/demonstration – The system will be demonstrated at an international airport.

Technical Progress

Excellent progress has been made during the course of the project. The design has been completed and the equipment is designed to scan people as they walk past the sensor.


The project has proceeded on the revised schedule with a completed design and manufacturing nearly finished. There have been several meetings of the Steering Committee and three review meetings with European Commission.
