WebAug 2, 2024 · The standard chirplet transform (CT) with a chirp-modulated Gaussian window provides a valuable tool for analyzing linear chirp signals. The parameters present in the window determine the performance of the CT and play a vital role in high-resolution time-frequency (TF) analysis. WebDec 1, 2024 · Hence, the chirplets that rotate in different angles at different frequency centers can exactly match all trajectories of the target multi-component signal if parameter a is set properly. We still take the signal x 2 (t) as an example to clarify the core thought behind CMCT. Similarly, we present this example in a window length range.
