Gabor multipliers revisited

Michael P. Lamoureux, Heather K. Hardeman-Vooys

Time-frequency methods have proven to be valuable in seismic data processing as localized Fourier transforms can accurately analyse the nonstationary characteristics of data in response to the non-uniform geology of the region under survey. For instance, Gabor deconvolution by way of Gabor multipliers is an effective way of extending stationary Weiner decon and spectral whitening to the nonstationary seismic domain.

We propose the continuous wavelet transform and its multipliers as an improvement over Gabor methods, using the logarithmically-spaced frequency bins in the CWT to improve resolution and control in the lower frequency range of the seismic signal.
