Greg Charvat earned his PhD in Electrical Engineering in 2007, and his dissertation described a low-power radar imaging system (PDF download). Now Dr. Charvat has made his dissertation available for anyone to download. This system uses the combination of a spatially diverse antenna array, a high sensitivity range-gated frequency-modulated continuous... Read more »

Greg Charvat coffee can doppler system in the field

Radio hacker extraordinaire Greg Charvat is back with this 15-minute video lecture showing off and explaining the measurement of moving objects’ velocities using the low-cost coffee can radar system he and co-workers at MIT developed, in the fall of 2010, for their open courseware initiative. The video begins with a... Read more »

Radio whiz Greg Charvat just published this video showing off a very cool experiment with the low-cost coffee can radar system he and co-workers developed, in the fall of 2010, for MIT's open courseware initiative. In the video, Greg describes and demonstrates a simple circuit that causes a red/green LED... Read more »

The MIT Open Courseware (OCW) radar materials from Dr. Gregory L. Charvat (and peers) that Matt blogged about back in February have just been released! This is hands-on education that my father, for one, spent a few years of his life (and no small amount of money) to acquire at... Read more »

Whats more hardcore than making your own synthetic aperture radar system? How about teaching a class how to build their own using some breadboardable electronics, empty coffee cans, and a spare laptop? That’s exactly what radio whiz Greg Charvat did this semester at MIT, and you can see some of... Read more »
