Three-axis velocity data, obtained along with pressure data in a marine seismic survey, are rotated to a ray direction. Plane wave decomposition is applied in the ray direction to the rotated velocity data. The pressure data and the velocity data are combined to generate at least one of up-going and down-going wave fields. The at least one of up-going and down-going wave fields are used in a time-space domain to image the earth's subsurface. Rotate three-axis velocity data, obtained 10 along with pressure data in a marine seismic survey, to a ray direction Apply plane wave decomposition in ray V11 direction to rotated velocity data Combine pressure data and velocity 12 data to generate at least one of up-going and down-going wave-fields Use at least one of up-going and down-going wave-fields in time- 13 space domain to image earth's subsurface |
