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.
