Abstract:
A system and method are provided for filtering scatterer noise energy from land seismic waves using three dimensional (3D) iterative filtering in a cross-spread source-receiver pattern. The system and method isolate scatterer noise energy associated with a scatterer based on a filtering process performed using a scatterer referential time delay. Then, the isolated scatterer noise energy can be subtracted from the surface wave data. This process can be repeated for each scatterer in the covered area to remove each of their contributions, and can be performed, for example, after a preliminary filtering of the surface wave data using 3D fk filtering or the like.
