Fast range point migration method for weapon detection using ultra-wideband radar

Radar-based security systems are of considerable importance because of their potential for detecting concealed weapons, particularly when they are in jackets or bags. To achieve this capability, the system has to achieve high-resolution and high-speed processing simultaneously. Many of the conventional technologies have focused on resolution, not speed. Recently, highspeed imaging methods for ultra-wideband (UWB) radars have been developed, amongst which the fast range-point-migration (RPM) method is the most promising technique because of its robustness against interference and noise. We apply the fast RPM method to measurement data with a mannequin and a gun to investigate the method's capability for detecting a weapon.
