FAQ - CHIRP

WebCHIRP frequencies allow you to sweep each pulse through a range of frequencies, resulting in better target separation in deep water. CHIRP can be used to distinctly identify targets, like individual fish in a school, and for deep water applications. CHIRP generally performs better than single frequency applications. 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.
