Application of the Karhunen-Loeve decomposition to localization of waves in slowness-time domain

(Akhmetsafin R.D. )

Proposed Hilbert-semblance (Slowness-Time Coherence) filtering through the Karhunen-Loeve decomposition. The purpose of filtering is the localization of the coherent power components of the wave packet sonic log (P-, S-, Lamb-Stoneley, etc.), which is blurred due to the heterogeneity of the velocity-properties of rocks between the receivers and noise.......
