Abstract:
The time-frequency peak filtering (TFPF) technology is applied for recovering seismic events without loss of valid information. By using frequency modulation signal encoding and taking peak of Wigner-Ville distribution (WVD) of encoded analytic signal, valid reflect signals constructing seismic events are estimated. To reduce the deterministic bias of TFPF resulted from nonlinearity of seismic reflect signal, the pseudo WVD (PWVD) TFPF is utilized. The reduced bias window length is derived by analyzing bias from experimental resulting. Testing of this method on synthetic seismic data and common shot point recordings indicates that TFPF technique significantly enhances signals from noisy seismic data and improves the continuity of seismic events by filtering out most of the additive noise. The resulting shows the clean recovery of seismic events in noise level down to a signal-to-noise ratio of-2.4dB.
