Abstract
A marine seismic survey is described which uses measurements made in a mid-field region of the source signature to correct an estimate of the far-field source signature as derived from individual contributions of the seismic source elements. The technique reduces the effects of perturbations which else have a considerable impact on the estimation of the far-field.
