Abstract:

Data processing is a basic and crucial factor in seismic exploration，which can influence the effect of subsequent processing directly． Thus the selection of appropriate method for data processing is one of the most important tasks throughout the work． By simulating，the authors analyze and compare Fractional Fourier Trans- form (FＲFT) and Wigner-Ville distribution (WVD)，then summarize the similarities and advantages and dis- advantages of the two methods． The results reveal that FＲFT is more effective and suitable for application in seismic exploration than WVD．

Keywords: seismic data processing Fractional Fourier Transform Wigner-Ville distribution
