Webfractional lower order linear chirplet transform and fractional lower order polynomial linear chirplet transform methods are demonstrated in Section 3, and simulation comparisons with the existing LCT and PLCT methods based on second order statistics are performed to demon-strate superiority of the improved methods. Weblower order polynomial is too smooth to fit accurately, while higher order polynomial approximation suffers from “Runge” phenomenon, which is a problem of oscillation at the edges of an approximation interval. To analyze the signal whose IF trajectory cannot be approximated by a polynomial, we then proposed spline chirplet transform (SCT ...
