Discussion Overview

The discussion revolves around an Arduino-based project that incorporates 3D ultrasonic sonar technology for various applications, including a virtual touch screen, real-time distance measurements, and ultrasonic radar capabilities. Participants explore the technical aspects, potential applications, and terminology related to sonar and radar.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant outlines the features of their Arduino project, including a virtual touch screen, 3D ultrasonic radar, and precise distance measurements using ultrasonic sensors.
  • Another participant corrects the terminology from "Radar" to "Sonar," explaining the difference between the two technologies based on the type of waves used.
  • Some participants discuss the broader applications of ultrasonic technology, mentioning its use in industrial contexts, such as refueling sodium-cooled reactors and other research areas.
  • There is a debate about the appropriateness of the term "sonar," with one participant suggesting it may imply underwater applications, while another argues that tracking objects in the air could still be considered sonar.
  • A participant shares a new video demonstrating the project, indicating ongoing development and exploration of the technology.

Areas of Agreement / Disagreement

Participants generally agree on the potential of the project and the distinction between sonar and radar. However, there is no consensus on the terminology used and the scope of research applicable to hobbyist projects versus industrial applications.

Contextual Notes

Some participants express uncertainty about the availability of research on small-scale, budget-friendly applications of ultrasonic technology, indicating a potential gap in the literature for hobbyist projects.

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.
