Abstract
A system and method for reducing noise in a seismic vibratory source is disclosed. The method includes generating an initial pilot signal for the seismic vibratory source, receiving a source signature based on the initial pilot signal, estimating a noise component of the source signature based on the source signature and the initial pilot signal, generating an anti-noise correction for the initial pilot signal based on the noise component of the source signature, and computing a modified pilot signal based on the initial pilot signal and the anti-noise correction.
