Hello! This is my first post and I was wondering about RF triangluation, I have read a few posts on rangefinding and such but I would like to pose a few questions.
I plan on having an fm transmitter transmitting on say 80mhz, the modulating frequency would be a physical wavelenght of say... 30meters (if anyone knows this formula, something with lambdaXfrequency and such...)
I would then have two receivers spaced apart in the room receiving and demodulating the signal leaving the modulating signal. I would then phase compare the two signals to get a compared voltage. This should give me a bearing in voltage right, by using trig?
Also I'm pretty new to this...I have seen some schematics for low power fm transmitters. I would like to have one that is crystal locked and variable to a few carrier frequencys(say 18, moved by dip switch) this way i could hold the transmitter and not affect the signal. The ones I have looked at have mics but I want to create a constant signal of 50khz(or whatever that 30m wavelenght is).
Once I get this phase compared voltage I can AtoD convert it with Arduino and throw it onto my comp right?
Any info would help thanks!
