P 158 Summary ATTENUATION OF SOURCE-GENERATED NOISE IN 3D CROSS-SPREAD DATA B. HEINCKE E. DUVENECK B. MILKEREIT and T. BOHLEN Institute of Geosciences Geophysics Kiel University Otto-Hahn-Platz 1 24118 Kiel Germany In cross-spread geometry source-generated noise( such as ground roll or refracted waves) generally shows rotational symmetry in respect to the center of the data cube. In order to make use of this symmetry to attenuate that noise a transform to polar coordinates followed by a 3D Fourier transform is applied. In the Fourier domain noise with rotational symmetry can be easily identified and removed. This filtering approach was applied
