METHOD FOR PERFORMING CONSTRAINED POLARIZATION FILTERING

摘要

An exemplary method for filtering multi-component seismic datais provided. The exemplary method comprises identifying a plurality ofcharacteristicsof the seismic data, the plurality of characteristics corresponding to arelative manifestation of surface wave noise on the different components andidentifying a time-frequency boundary in the seismic data, the time-frequencyboundary delineating portions of the seismic data estimated to contain surfacewave noise (302). In addition, the exemplary method comprises creatingfilteredseismic data (306) by removing portions of the seismic data that correspond tothe plurality of characteristics of surface waves and that are within the time-frequencyboundary (303).
