Abstract
Computing device, computer instructions and method for directional designature of seismic data d with a given source directivity. The method includes obtaining directional operators r; calculating a model u with a modified source directivity based on (1) seismic data d, and (2) an operator that is a combination of the directional operators r and a reverse transform operator L; using the model u to obtain seismic data dfree with modified source directivity; and generating a final image of the subsurface using seismic data dfree.
