资源简介:
a) The synthetic velocity model used in the first numerical example.The model consists of two layers with irregular boundary (refractor) andthickness ranges between 2m and 6m. The velocities of the first and secondlayers are 650 m\/s and 1400 m\/s, respectively. b) The calculated traveltimesused as input data to the LS-ESVI. The figure shows 504 CSGs and48 receivers per shot. c) The calculated traveltimes used as reference forcomparison with the extrapolated data. We calculated 600 CSGs, however,this figure shows only 504 CSGs and 84 receivers per shot that were used inthe extrapolation. CSGs 505 to 600 are required to have a complete coverageat the extrapolation process.
