Some Applications of Wavelet Transform to Noise of Surface Wave

Seismic data noise attenuation is a very important part of seismic data processing. With the advancement of exploration techniques,more and more geophysical methods can be used in noise attenuation. Currently the wavelet transform is relatively a better methods. Wavelet transform are widely used in seismic data noise attenuation with its unique time--frequency characteristics. Compared with the previous frequency filter,it is visible superiority. In this paper,we briefly introduces the wavelet function as well as the methods of wavelet noise attenuation,then combined with the realities of wavelet noise attenuation was introduced.
