Forward and backward amplitude and phase estimation method for dispersion analysis of borehole sonic measurements

We have developed a nonparametric matched filter-bank spectrum estimator, referred to as the forward and backward (FB) amplitude and phase estimation (FBAPES) method, to perform dispersion analysis of borehole array sonic measurements. Different from conventional dispersion analysis methods, the amplitude and phase estimation method estimates the dispersive properties of wave modes by simulating the statistical character of interferences from...
