VECTOR-DIP FILTERING OF SEISMIC DATA IN THE TIME-FREQUENCY DOMAIN

摘要

Methods and systems for separating surface wave velocity informationfrom surface wave noise in seismic data are described. The seismic data can becomprised of irregularities in spatial sampling, non-stationarity in time andnon-stationarityin frequency. The methods and systems can then be adapted tocreate a multi-component dip filter that removes high amplitude dispersivenoisefrom the seismic data based on the use of slant stacking.
