DIY Radar Kit Will Set You Back a Cool $600
While I’m a trifle puzzled how the kit could cost six hundred bucks, I love the idea of building a radar! It’s based off of Gregory Charvat’s coffee can radar project. The QM-RDKIT Radar Demonstration Kit from Quonset Microwave is an ideal tool for use in the classroom for learning about Radar and for the […]
Gregory Charvat’s Radar Dissertation Now Online
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 wave (FMCW) radar system, and […]
Hacking a Police Radar
Gregory “Mr. Vacuum Tube” Charvat breaks down an old school police radar.
DIY Coffee Can Radar
MIT student Timur Balbekov built this coffee can Doppler radar. Wanna build your own? MIT offers a free online guide telling you how. (Can anyone tell me what microcontroller Timur used?) [via Mr. Vacuum Tube]
Radar Gun Connected to Stereo System
In this off-the-cuff video, MIT prof and MAKE pal Gregory Charvat shoots Nerf darts into the beam of an old X-band Doppler radar gun with its output hacked into a linear power supply, a preamp, and finally into Greg’s living room stereo system. The signal sounds like a cartoon sound effect!
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 […]
