"WebIf the demodulation window is perfectly aligned with the signal, then the peak of the up-chirp and peak of the down-chirp appear at the same frequency, regardless of the CFO, as shown in Figure 5. Otherwise, there is a significant difference in the frequency of the two peaks, depending on the time offset between the chirp and the demodulation ... " - Chirp demodulation github
