Seismic wavelet estimation based on the high-order spectrum

HUANG Jian-ying,LI Lu-ming,LUO Sheng-xianCollege of Information Engineering,Chengdu University of Technology,Chengdu 610059,China  
The wavelet is usually presupposed the minimum phase in wavelet estimation.In order to get rid of the limitation,a new wavelet estimation method based on the high-order spectrum of seismic data is brought forward in this paper.There is no any presumption of the wavelet for this method.Using bispectrum of seismic,the phase spectrum and amplitude spectrum of the wavelet is recovered and the wavelet is restructured.The processed results of synthetic data with different wavelet phases and real data show that the method is feasible and promising in improving the resolution of seismic data.
