Abstract: Computing device, computer software and methods for generating sweep signals corresponding to plural sources that generate seismic waves. The method includes selecting (502) a nominal sweep signal (S0); applying (512) a perturbation (P) to the nominal sweep signal (S0); and calculating (518) the sweep signals (Sn) by varying the perturbation (P), each sweep signal corresponding to a seismic source.

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.
