【Abstract】 To improve the signal noise ratio (SNR) of seismic data, the relationship between optimum median filter length and wavelength, the time shift between traces or frequency, and the apparent velocity are studied through the median filter experimental analysis on seismic model lamination. The formulation of optimum median filter length, which is deducted and proved by the theoretic model and real data, can achieve satisfied results.更多还原
