Hey Mike,
So the purpose of using two out-of-phased signals is to know the relative location of the target; either behind, near, in front, or etc relative to my position...correct? Will the amount of phase shift or any other aspect of the two signals give a clue about the distance from me to...
Hey Mike,
Its cool that you worked with someone very talented in engineering before with my name!
Anyways, I think I'm not making myself clear in my theory... First, assume the relative speed between me and a target is fixed. When the target is moving towards my radar, the receiving...
Unfortunately, I cannot sweep the frequency. The unit only takes an "enable" signal and it continuously sends out "bursts" of RF energy at a fixed frequency and outputs a signal relative to the amount of doppler shift. I'm not so sure of using my hearing involved in this project; but it does...
Hey all,
I'm a newbie here with a question regarding doppler shift. Before I ask, I only have a very basic understanding of the doppler effect.
So, my big question is: can a doppler shift measurement be converted to the distance between the source and target, without using the time of...
Actually, this isn't a science fair project (although I did enter part of my project into the science fair). This is my hobby and I plan to sell it to some major company to mass produce it. To answer your questions, the range I'm aiming for is from one or two inches to 100 feet. Accuracy will...
I already have all the electronics and everything planned out and to be simulated (electronics is basically my living). The only part where I really lack is optics; which I need to patch it up before I can move on.
Hi, I'm new to this place, and I'm not sure if my problem fits with this forum, but I'll give it a try.
Right now, I'm building a laser range finder, but my biggest concern will be focusing the reflected laser beam onto a small silicon photodiode. And to add to that, I have barely any...
