Using Walsh transform to improve signal-to-noise ratio of seismic data
Online published: 2009-09-16
The filter technique based on Walsh transform is used to suppress seismic noise in order to improve the signal-to-noise ratio of seismic data. This method uses the spectrum analysis of seismic signal to realize the noise suppression. Through estimation of theoretical model and application in the real seismic data, this method has a nice effect in elimination the noise of seismic data. This method is very simple to realize and very fast to calculate. It has a good practicability in suppressing noise and increasing the signal-to-noise ratio of the seismic data.
