Hello,
I am brainstorming an idea in which I need to know the exact location of a signal within all 3 dimensions. The area in which this signal would emanate is a 1 cubic foot area that could be anywhere between 6 and 36 inches away from the sensors.
My current idea is to use multiple sensors to triangulate the location and use signal strength to gauge the distance to each sensor. I need to be able to sense the distance within 1/8th inch or less in order to make an accurate calculation. That being said, I have also considered taking many more readings than the minimum 3 and averaging the result if necessary.
Here is my question to all of you: Do you know of a product that can guage signal strength with the precision I am looking for? I do not have a signal source that I need to use so if there is a product that has both the transmitter and reciever and can tell the distance between them then that would be great.
The situation in which I need this cannot use IR so unfortunately that is not an option. Other than that, if anyone has any other ideas for accomplishing this task, I would love to hear them.
