Washington: A new radar technologydeveloped at MIT’s Lincoln Laboratory has brought science fiction into reality with its ability to see through walls. The technology can provide real-time videoof what’s going on behind solid walls, Science Daily reported. Much as humans and other animals see via waves of visible light that bounce off objects and then strike our eyes’ retinas, radar “sees” by sending out radio waves that bounce off targets and return to the radar’s receivers. But just as light can’t pass through solid objects in quantities large enough for the eye to detect, it’s hard to build radar that can penetrate walls well enough to show what’s happening behind. The researchers’ device is an unassuming array of antenna arranged into two rows – eight receiving elements on top, 13 transmitting ones below – and some computing equipment, all mounted onto a movable cart. It has powerful implications for military operations, especially “urban combat situations,” said Gregory Charvat, technical staff at Lincoln Lab and the leader of the project.
