Concealed Weapon Detection (CWD) has become a significant challenge to present day security needs; individuals
carrying weapons into airplanes, schools, and secured establishments are threat to public security. Although controlled
screening, of people for concealed weapons, has been employed in many establishments, procedures and equipment are
designed to work in restricted environments like airport passport control, military checkpoints, hospitals, school and
university entrance. Furthermore, screening systems do not effectively decipher between threat and non-threat metal
objects, thus leading to high rate of false alarms which can become a liability to daily operational needs of
establishments. Therefore, the design and development of a new CWD system to operate in a large open area
environment with large numbers of people reduced incidences of false alarms and increased location accuracy is
essential.
