Abstract:

Wavelet processing is an important processing method in xiamic data proeessing. This paper proposes a new wavelet processing method,which is to use zero—phax symmetry of wavelet's auto—correlation based on a known wavelet,and to make deconvolution according to the least square method to obtain a zero—phase compressive pulx. Tested by rnmputer. the method proves to be much more improved than the original wavelet processing method.

Key words: seisthic data processing, wavelet processing, Zero-phase symmetry
