| Abstract: | The time-frequency distribution of Smoothing Pseudo Wigner-Ville distribution （SP-WVD） was introduced in the paper, the definition of analytic transformation was presented together the method of Real signal. The method of SPWV time-frequency distribution was given. The method was used to explain the attributes of seismic signal. The results show that SPWVD can illustrate the behaviour of time-frequency localization and the character of nonstationary signal, the SPWVD can be a effective way to illustrate the behaviour of time-frequency localization of seismic signal. |
