seismic data through removal of non-stationary wavelet in cepstrum domain. Algorithm
incorporates useful properties of both homomorphic deconvolution and spectral
decomposition by this way it estimates and filters the wavelet at each translation
of spectral decomposing Gaussian window which improve the resolution and tolerates
the non-stationary properties of seismic wavelet. This study describes the comprehensive
mathematical formulation of the algorithm and its testing on 1D, 2D synthetic
and real seismic section to confirm its applicability. Comparative testing shows
that the algorithm effectively removed the smearing effect of wavelet which
led to broader frequency spectrum and improved seismic resolution.]]>Allen, J.B. and L. Rabiner,1977Auger, F. and P. Flandrin,1995Buhl, P., P.L. Stoffa and G.M.
