| 摘要 |
A seismic system is provided with a method of reducing distortions caused by motion of a source (112) and receiver (114) in marine seismic measurements. In one embodiment, the seismic system comprises a seismic source (112), a seism ic receiver (114), a source/receiver interface unit (56), a processing unit (53 ), a data storage unit (54), a display device (52), and a user input device (59 ). The processing unit is configured to receive seismic measurements from the seismic receiver and to create a seismic velocity model from the received data. The processing unit uses the velocity model to calculate a dilation function that is indicative of distortion caused by motion of the seismic source. The dilation-compensated data for varying constant-dip slices are combined to yield seismic data corrected for source and receiver motion.</SD OAB>
