Abstract：The Chirplet Transform（CT） have being become one of the most popular field in signal processing, which is extend from the Wavelet Transform（WT）. This paper calculate the Gaussian Chirplet Transform（GCT） by the Short-Time Fourier Transform（STFT）. At the same time, its parameters is optimized by making use of FRFT and Generalized Time-Bandwidth Product（GTBP）. Compared with WVD and STFT, GCT has been show excellent performance for the time-frequency concentration.
