MIT Researchers' New Radar Technology Sees Through Walls

The device can detect what’s going on behind 8-inch concrete.

Researchers at MIT’s Lincoln Lab have developed a radar system that can “see” through concrete walls up to eight inches thick. Developed with an eye toward military applications, the device, it’s claimed, can operate from 60 feet away. Using wavelengths similar to those employed by Wi-Fi, the device yields real-time video of moving objects behind walls. Currently, the systems displays moving things – such as people – as blobs that researcher Gregory Charvat said in an MIT news release “requires a lot of extra training” to understand. But Charvat and his colleagues are working on enhancements to improve the images. To see the system in action, watch the video below.
