An electrical engineering professor at the University of Michigan believes that a type of radar, part developed by the Department of Defense, has the potential to be used as a means of detecting concealed weapons. Originally intended for military use, it is possible that the millimeter-wave radar system could be used to detect weapons across distances as large as a football field.
Professor Kamal Sarabandi was watching the aftermath of the Newtown shooting in Connecticut when he was hit by the notion that his work for the military may have a use a little closer to home.
The technology that he developed is currently being used in a number of applications, including collision avoidance systems in cars and in military targeting systems. The radar itself isn’t particularly unique, but Sarabandi’s pairing of the tech with Doppler radar signal processing allows it to pick out an individual in a crowd using a technique called polarimetry.
