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.
