Ridgelet domain method of ground-roll suppression

Ground-roll is a regular interferential wave existing widely in seismic data, and it is a difficult problem in seismic data processing to suppress ground-roll. The traditional methods can do these to some extent, but they only use the ground-roll single characteristic during processing. We gain a transform which is valid in seismic processing, namely, Ridgelet transform. It can transform seismic data in (x, t) domain to (a, τ,p). So we can use the difference in velocity, time and scale characteristics of seismic data to process and separate different waves at the same time. Examples of processing the synthetic and real data illustrate its feasibility and effectiveness of the Ridgelet transform method in attenuating ground-roll.
