High resolution seismic processing based on whitening of Hilbert spectrum
Abstract：Conventional spectral whitening method cannot improve the detailed information of both time domain and frequency domain at the same time,to amend this problem,a novel method was proposed to improve the resolution of seismic signal by whitening its Hilbert spectral.This method decomposed the signal in time-frequency domain by the Hilbert-Huang transformation,and then applied the whitening filter to its Hilbert spectral.After comparing this new method with conventional method by applying them to synthetic seismic data and real seismic data,the results show that the new method can improve the resolution of signals both in time and frequency domains effectively while keeping a high S/N ratio,and improve the continuity of events in seismic profile.
