First Pictures From the Pegboard Phased Array Radar

Yesterday I mentioned MIT’s soon-to-be-released open-courseware materials detailing a DIY phrased radar array radar system built from pegboard and wi-fi antennae. The project, from MIT engineers Drs. Bradley Perry, Jonathan Paul Kitchens, Patrick Bell, Jeffrey Herd, and Greg Charvat produces ‘radar video’ at about three frames per second. Greg just e-mailed me a link to […]
