Study of seismic wavelet extrapolation based on high-order statistics method

Due to lack of analyzing tools,it has been always assumed that seismic wavelet is minimum-phase and reflection coefficient is Gaussian distributed.However,in most circumstances,this kind of assumption does not match with the actual situation.Based on the higher-order statistics method,the estimation method of non-minimum wavelet was put forward,which was suitable for any Gaussian noise.Two novel classes of analysis tools in signal processing—higher-order statistics were presented.Through the application in seismic data processing,numerical data tests demonstrate that the method is capable of mix phase wavelet with relatively higher accuracy.
