Abstract: Systems and methods are disclosed for attenuating noise during seismic acquisition. The method includes compiling a seismic data set from data received by a plurality of receivers. The seismic data set includes noise energy from a noise source. The method further includes calculating a plurality of cross-correlation panels based on a reference trace from a reference receiver. The reference receiver is one of the plurality of receivers. The method includes estimating the location of the noise source and applying a correction to the plurality of cross-correlation panels based on the estimated location of the noise source generating a plurality of corrected panels. The method also includes analyzing the plurality of corrected panels for a noise operator to attenuate noise in the seismic data set.
