摘要
线调频小波变换是处理非平稳信号一种新的方法 .本文分析了线调频小波变换是短时 Fourier变换和小波变换的时频分析的统一形式 ,并能根据信号的特点生成新的时频分析方法 。
In this paper, a new signal processing method, chirplet transform(CT), is described using in the area of non\|stable signal. Chirplet transform is the time-frequency uniform of STFT and WT and can make new time-frequency analysis methods according to the features of signals. These show the advantage of CT.
