Kwick Millimeter Wave Imaging Systems

Concealed object detection is one of the greatest challenges facing security operations today. To detect concealed objects requires more than metal detectors in today’s environment. There must be reliable ways to detect and identify non-metallic items or other threatening objects that may be concealed under clothing. Millimeter wave (MMW) frequencies readily penetrate clothing, thus allowing the detection of hidden objects.

Why Millimeter Wave Technology

Millimeter Waves (MMW) describes a very high frequency range whose “wavelength” is on the order of a millimeter. MMW energy occurs naturally in objects (all material types) and environments and can be sensed accurately by specialized equipment.
Clothing and similar materials are transparent at MMW frequencies and thus well-suited to MMW imaging for concealed object detection. Images can be collected in passive (listen only) or active mode. Passive imaging creates no concerns or perceptions regarding individual privacy and health

Key Elements of Detection

Contrast (Signal/Background Ratio)

Body-to-surrounding environment temperature difference (the higher the difference the better the contrast)
Concealed object-to-body contrast – This is a function of temperature difference and emissivity difference
External interferences – A site survey will minimize impact

Object Size

Larger objects are easier to detect
Larger areas of contrast on the body (abdomen versus legs) make detection easier

Location of Concealed Object

Higher detection or lower false alarm
Detection accuracy versus screening time
Multiple cameras versus screening time

Trade-offs

Higher detection or lower false alarm
Detection accuracy versus screening time
Multiple cameras versus screening time

Operational Scenarios


Walk-Through

Walk-through screening allows real-time detection of concealed objects while the subject transits through the screening area. The detection can be non intrusive where the passive system can be hidden behind opaque walls. In this scenario, two passive systems are recommended for better body coverage.



Cooperative Spot Screening

Cooperative spot screening allows random or systematic subject screening for small concealed objects.



Note: To maximize the efficiency, use walk-through metal detectors on entrance
