Abstract

Summary: We present the theory and numerical results for interferometrically interpolating 3D marine surface seismic profiles (SSP) data. For the interpolation of SSP data we use the combination of a natural Green's function (SSP shot gathers) and a modelbased Green's function for the water-layer model. Synthetic results show that the aliased SSP data with sparse receiver intervals can be accurately interpolated to smaller intervals. The virtual shot gather contains some artifacts so a non-stationary 2D multi-channel image matching filter is used after interferometric interpolation to remove these artifacts. Results suggest that a sparse marine SSP survey can yield more information about the reflectors if data are interpolated by interferometry. This assumes that the sources are located both outside and above the recording aperture.
