I am trying to construct for a class project a device
(computerized) that can determine the correct resonant frequency of an
object at a range.
So far, I have determined that I should send out a "chirp" of a lot of
what to look for in the echo to indicate what the fundamental frequency
Any ideas on how I could determine this?
I guess I'd take a Fourier transform of the chirp and compare it to a
Fourier transform of the echoed waveform.
