WebMar 14, 2013 · The chirp signal shows different frequencies at different times but FFT looks the whole signal (all times) and to achieve that I imagine it generates higher harmonics. There is a reason the matlab example plots a spectrogram and doesn't take an FFT and that is because the FFT of the chirp isn't really a generally useful thing to do. WebNov 1, 2024 · The chirp may have a positive frequency slope with time (up-chirp) or a negative frequency slope with time (down-chirp). There is no inherent advantage to one with respect to the other, except that the receiver needs to be matched to the proper waveform.
