Sharp Deconvolution in p-tau domain.




Testing SDec in a fully automatic mode
with blind synthetic 1.5 D data. Model 2 (a posteriori)

Model # 2: P-velocityModel # 2: S-velocityModel # 2: Density
Movie: input/SDec-outputs for the Model 2
Movie composed with the P-Tau Input and SDec-outputs for the model 2:
the input:         blind data, no a priori information;
the 1st SDec output:  no free-surface related multiples;
the 2nd SDec output:  sea-floor related intrabed multiples are removed;
the 10th SDec output: all of intrabed multiples are removed.
The column on the left:   theoretical impulse trace: normal incidence.
