Non-invasive concealed weapon detection and identification using V band millimeter wave imaging radar system

This paper presents a millimeter wave imaging radar system operating at 60 GHz for non invasive and nondestructive concealed weapon detection and identification. In order to mimic, the concealed weapon target, an aluminum toy gun covered with cloth has been used. Different signal processing techniques were applied in order to fully detect and identify the concealed weapon target. Techniques like; discrete convolution, mean and standard deviation based thresholding and canny edge detection were applied and their applicability was tested towards successful hidden target identification. The correct target location and shape identification validates the MMW radar´s capability towards standoff concealed object detection and identification. Further, the proposed technique can be used with other different kinds of weapon targets for applications requiring personal screening and security check.
