Abstract
This project investigated the feasibility of ultra-wideband (UWB) high-resolution radar in the detection of concealed weapons with a focus on weapons hidden un-der clothing. A prototype system was built. The prototype system involved a frequency-sweep test setup using a vector network analyzer. Measurements under realistic conditions (cluttered environment) were carried out at McMaster University where volunteers from the military police participated and carried (unloaded) guns or knives. The preliminary results suggest that microwave radar working in the fre-quency range from 500 MHz up to 5 GHz can indeed uncover the presence of weapons hidden under clothing at a range of about one to two meters. The detection is not strongly dependent on the position of the person or on the clothing. Small objects such as mobile phones and keys do not seem to a4ect significantly the performance.
