The First Arduino Radar Shield

The very first fully operational radar Arduino shield was recently demonstrated at Bay area Maker Faire. It was built by [Daniel] and [David], both undergrads at UC Davis.

Many have talked about doing this, some have even prototyped pieces of it, but these undergrad college students pulled it off. This is the result from Prof. ‘Leo’ Liu’s full-semester senior design course based on the MIT Coffee Can radar short course, which has been going on for 2 years now. Next year this course will have 30 students, showing the world the interest and market-for project based learning.

Check out the high res ranging demo, where a wider band chirp was used to amazing results. Video below.

  1. Very cool, just be sure to operate within the laws of whatever jurisdiction you live in, as any application of active radar involves transmitting RF.

  2. ” showing the world the interest and market-for project based learning. yet again showingWe the influence of hackers on higher education.”

    Even by HaD’s editorial standards, this is diabolical. Come on chaps – at least read it through once before you post.

  3. For those who like to experiment with this stuff in a simpler way, take a look at the HB100 doppler sensor module. It costs a few bucks and meets all legal/safety requirements.

    1. RF radiation at this level isn’t going to do anything to you. It’s a myth about cops and testicular cancer and traffic enforcement radar. On a larger radar with much higher output power, kilowatts on up you might get thermal injuries and cataracts due to tissue heating, since radar typically works at microwave frequencies and work pretty much the same way as your microwave oven, though the guts may not be just a simple magnatron like in an oven. This is non-ionizing radation and does not emmit “rays” like as in x-rays or gama rays.
