RADAR Flashlight: Hi-tech tool could assist crime fighters in critical situations
Researchers at the Georgia Tech Research Institute (GTRI) have developed a RADAR Flashlight which they claim would be of tremendous value to police officers enabling them to see behind enclosures while remaining undetected. 'A prototype device called the RADAR Flashlight, developed at the Georgia Tech Research Institute (GTRI), can detect a human's presence through doors and walls up to 8 inches thick. The device uses a narrow 16-degree radar beam and specialized signal processor to discern respiration and/or movement up to three meters behind a wall. The device can penetrate even heavy clothing to detect respiration and movements of as little as a few millimeters.'
