摘要
A method and apparatus implementing a technique for mitigating noise in seismicdata are presented. The technique includes estimating a noise component in aset of multicomponent seismic data representing a recorded wavefield from therelationship at the free surface of an upgoing component and a downgoing componentdecomposed from the recorded wavefield; and removing the estimated noise componentfrom the seismic data. The noise component can be estimated by decomposing a recordedwavefield into an upgoing component and a downgoing component and isolatinga noise component in the recorded wavefield from the relationship of the decomposedupgoing and downgoing components at the free surface.
