This file contains the function for Chirplet Transform ("Chirplet_Transform.m") of a 1-D discrete signal, and the time-frequency representation of a bi-LFM signal in Chirplet Transform with them in STFT(STFT.m) & Wavelet Transform(CWT_Morlet.m) .

Just run "TEST1.m" to see all the results mentioned above.

Codes written by Guowei Tu (now in School of Mechanical Engineering, SJTU, contact me via GuoweiTu@sjtu.edu.cn).

The Original Chirplet Transform Algorithm is introduced in [1]; while the codes here is motivated by [2], which provides a new insight to the Chirplet Transform.
