Abstract
Systems and methods according to these exemplary embodiments provide for attenuating noise which interferes with recordings of a seismic source. A method includes: generating a reference trace for a noise source; generating a primary trace for the seismic source; generating a first estimated convolutional operator between the reference trace and the primary trace; convolving the operator with the reference trace for a time frame to generate an estimated noise for the time frame; and subtracting the estimated noise from the primary trace to generate an output signal.
