| 摘要 | Apparatus, computer instructions and method for processing seismic data related to a subsurface of a body of water. The method includes inputting data indicative of recordings made by detectors provided on a curved profile in response to an acoustic wave reflected from the subsurface; applying a matched mirror migration procedure to the data, where (i) actual positions of the detectors on the curved profile and corresponding recordings, and (ii) fictitious mirror positions of the actual detectors on the curved profile and corresponding recordings with a changed sign are added in the matched mirror migration; and generating a final image of the subsurface based on the matched mirror migration procedure. | ||

| 主权项 | 1. A method for processing seismic data related to a subsurface of a body of water and displaying a final image of the subsurface on a display, the method comprising: inputting data indicative of recordings made by detectors disposed on a curved, parameterized, depth-changing profile in response to an acoustic wave reflected from the subsurface; applying a matched mirror migration procedure to the data, wherein the matched mirror migration procedure uses a wave constructed based on (i) actual positions of the detectors disposed on the curved, parameterized, depth-changing profile and corresponding recordings, and (ii) fictitious mirror positions of the actual detectors on the curved, parameterized, depth-changing profile and corresponding recordings with a changed sign; and generating with a computing device the final image of the subsurface based on the matched mirror migration procedure. | ||
