Fourier transform(FT)and wavelet transform(WT )are widely used in many area.In this paper,two new signal processing method,chirplet transform(CT)and Dopperlet transform(DT),are described to process non-stable signals based on recalling the evolution of FT and WT.Chirplet transform is the time-frequency uniform of STFT and WT ;FT,WT and CT are special case.These show the advantage of CT and DT.CT and DT are new methods and tools to process signals and images.
