Radar Flashlight LLC has been formed to exploit the development by Georgia Tech Research Institute (GTRI) researchers of a prototype RADAR flashlight that allows the user to detect a stationary individual located behind a solid wooden door, or standing four feet behind an eight-inch block wall. Using a radar beam of 15 to 20 degrees and a specialized signal processor to discern respiration from up to three meters away, with no physical connection between subject and radar. The RADAR flashlight offers two advantages over other technologies: Its signal penetrates clothing, and the flashlight requires a body movement of only a few millimeters to detect human presence. A provisional patent application for the device has been filed. The signal processor is outside the flashlight-sized casing, and the respiration signature is displayed on a monitor. Plans are to make all the equipment small enough to fit inside the flashlight housing.
