Abstract

A football-sized array of magnetic sensors can detect blades, knives, handguns and vehicles in the vicinity. Immediate analysis can show the concealed target as a red blob that is superimposed on a video image. This paper reviews why Linux was the only viable platform, describes the software and summarizes the algorithms being used.
