Assuming that the signals start out with zero offset, and then one becomes progressively delayed (like Doppler shift from a receding object), you would need to resample the slower one (W2'(t) = W2(kt), k > 1) by different amounts and see where the correlation peaks. If there is no underlying phenomonology to suggest that this should happen, it would probably be a waste of time. Either way, I'll leave it to you.  Reply With Quote

Ahhh I get you, We start out with a zero offset from the source of the wave, but there are two receivers detecting that wave which are slightly offset. It's this difference that we use to calculate the velocity of the wave.  Reply With Quote
