Polarity preserving decon in ``N log N'' time

Polarity preserving decon in ``N log N'' time

Jon Claerbout

Abstract:

A slight modification to Fourier spectral factorization enables deconvolution to preserve and enhance seismogram polarities. It spikes the center lobe of the Ricker wavelet. It works by tapering at small lags the antisymmetric part of the time-domain representation of the log spectrum.
