Radar flashlight" lets cops spot people through walls
Radar flashlight" lets cops spot people through walls
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.
