Wavelet Estimation and Processing Using High-order Accumulation Method

Wavelet processing, in which wavelet estimation is essential, is an effective technique for improving the resolution of seismic data. Based on the fact that higher order accumulation retains the phases of signal information, a method of wavelet estimation using bispectrum of seismic signal is developed in this paper. The examples of synthetic data with different phase property of wavelet show that the method is feasible, and the examples of field data also show that the higher order spectra of signals are promising in wavelet processing and resolution improvement.
