Thin-bed prestack spectral inversion

WebDip-steered mean filters work well on prestack data in which discontinuities appear as smooth diffractions, but smear faults and stratigraphic edges on migrated data. Dip-steered median and alpha-trimmed mean filters work somewhat better but will still smear faults. Hoecker and Fehmers (2002) address this problem WebThe inversion process can put anything there, and the original Conclusions and discussion seismic data will be recovered when the output sparse spike The thin-bed spectral …
