De-aliasing high resolution τ-p transform and its application to wave fields separation

The τ-p transform is one of the important techniques to eliminate coherent noises and separate wave fields,but the operator aliasing artifacts and edge effect artifacts affect its resolution,therefore the conventional τ-p transform can't be used simply.This paper presents a new non-iteration high-resolution τ-p transform procedure which can suppress aliasing artifacts and edge effect artifacts simultaneously and improve resolution.The results show that the new procedure is effective by processing the synthetic seismogram and real data.
