Yes, you read that correctly.
No hard technical details are out yet, but this amazing project from MIT radar hackers Drs. Bradley Perry, Jonathan Paul Kitchens, Patrick Bell, Jeffrey Herd, and MAKE regular Gregory L. Charvat is soon to be published as part of MIT’s open courseware initiative. Cost of parts is about $950. The course abstract describes a “laptop-based phased array radar sensor capable of imaging moving targets in real-time, like a ‘radar video camera’.” [Thanks, Greg!]
