Abstract
Seismic reflections are sometimes masked by Rayleigh-type surface wave s that are termed ground roll in seismic literature. An adaptive latti ce 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 th e signal, and increases the signal-to-noise ratio.
