A Review of Concealed Weapon Detection and Research in Perspective

This paper reviews recent developments in the area of concealed weapon detection using largely electromagnetic methods including metal detection, magnetic field distortion, electromagnetic resonance, acoustic and ultrasonic inspection, millimetre waves, Terahertz imaging, Infrared, X-ray etc. The advantages and disadvantages of these approaches are discussed. Research challenges are presented. Future research perspectives are presented and our joint research project has also been introduced.
