Amplitude Calculation for 3-D Common Offset v(z) Inversion

摘要

The general 3-D inversion formula developed by Bleistein et al., is specializedto a depth-dependent medium. An efficient ray tracer for this model is developed to calculate the necessary constituents of the ray theory. The traveltime and amplitude tables for the inversion are computed. The motivating application for this project is detection of small objects-10cm-in shallow water-10-20m.
