Defcon 19: build your own radar system
At the Defcon 19 (2011) conference Michael Scarito demonstrated how to construct your own radar system. The project is based on a design by Dr. Greg Charvat from MIT and uses synthetic aperture techniques to generate a two- or three-dimensional image. (You can read Dr. Charvat’s research paper here.) The hardware operates in the 2.4 […]
Homemade TSA type body scanner
Geek guru Jeri Ellsworth is at it again, continuing with her exploration of homebrew radar devices. In this installment satellite dish hardware is interfaced with an FPGA to provide Via Hack A Day.
Speed radar demo using toy radar gun module
Here’s another cool tech video by Jeri Ellsworth, this time illustrating how speed radar works using parts from a toy radar gun. Also refers to similarly using a satellite TV LNB module.
