THE LATTICE FILTER IN GROUND-ROLL SUPPRESSION

1994    SAATCILAR, R; CANITEZ, N

Seismic reflections are sometimes masked by Rayleigh-type surface waves that are termed ground roll in seismic literature. An adaptive lattice filter is used to recover reflected signals contaminated by ground roll. Experiments on synthetic and field data showed that the adaptive lattice filter technique is very effective in ground-roll elimination. In addition, the filter works as a whitening operator, compresses the signal, and increases the signal-to-noise ratio.
