Ricker-compliant deconvolution
نویسندگان
چکیده
Ricker compliant deconvolution spikes at the center lobe of the Ricker wavelet. It enables deconvolution to preserve and enhance seismogram polarities. Expressing the phase spectrum as a function of lag, it works by suppressing the phase at small lags. A byproduct of this decon is a pseudo-unitary (very clean) debubble filter where bubbles are lifted off the data while onset waveforms (usually Ricker) are untouched.

Polarity preserving decon in “N log N” time
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.
متن کاملNonminimum phase deconvolution in the log domain: A sparse inversion approach
Being disturbed by the discrepancy between the Ricker wavelet and minimum phase wavelets, we wondered if a sparseness criterion could get us deconvolved data with the event polarity being more clearly evident. Five data sets found it does. The sparseness criterion we used is a hyperbolic penalty function. It ranged from l2 at small residuals to l1 at large residuals. The main pitfall was that i...
متن کاملSix tests of sparse log decon
Previously, we developed a sparseness-goaled decon method. Here we test it on six data sets. None showed the unfortunate phase-shift we always see with minimum-phase decon. None showed the polarity reversals or time shifts that perplexed our earlier work. Results on all six data sets enhance polarity visibility. We had expected to see sparseness decon limit the bandwidth in some natural way unl...
متن کاملDeconvolution of Point Sources: A Sampling Theorem and Robustness Guarantees
In this work we analyze a convex-programming method for estimating superpositions of point sources or spikes from nonuniform samples of their convolution with a known kernel. We consider a one-dimensional model where the kernel is either a Gaussian function or a Ricker wavelet, inspired by applications in geophysics and imaging. Our analysis establishes that minimizing a continuous counterpart ...
متن کاملUsing the Grid in the Mouse Atlas Project
This paper presents initial results of investigating and developing grid-enabled tools for collaborative image processing, visualisation, and database access within the context of the mouse atlas project at the MRC Human Genetics Unit. OGSI compliant grid services for compute intensive task in the mouse atlas have been investigated and a grid service has been developed to implement a grid-enabl...
