I'm working on arduino based project, that actually can perform 3 features:

1. Virtual Touch Screen, for remote control purposes big screen TV, projectors, public display, or for interactive games
2. 3D Ultrasonic Radar, small range - 3 m for now, but real time with update rate 50 fps;
3. Precise distance measurements , down do 12 micrometers.

FFT is the major part of software application running on arduino DUE (cortex-3 , ATMEL SAM3X8E), plus 4 very popular ultrasonic distance sensors HC-SR04. Extracting the phase of returning ultrasonic wave, great precision in distance measurements possible.

More details on the blog page:

and two demo video clips on youtube channel:

Opinions and suggestions are welcome.

Sounds like an interesting project. BTW, I changed "Radar" to "Sonar" in your thread title. Radar uses radio waves, and Sonar uses sound (or ultrasound) waves. :smile:
 
There's a lot of research on that subject. They use it for refueling of sodium cooled reactors because you can't see through sodium.
A friend did electronics work for Bechtel , making high powered drivers for the transducers.

A quick search turned up lots more applications than i could have imagined:

You're on to something there. Have fun !

Agree, I missed this out. Same time sonar term sounds too specific, related to underwater localization. Tracking object in the air brings radar to mind
There's a lot of research on that subject.
True, but all of them industrial or military. I don't know any research on small, "hobbyist" scale, with a budget < 100$.
New video posted, radar, hmm, sonar relaying a data to android application.
