| 英文摘要 | Based on the one-way wave equation, we develop the schemes to calculate the travel time, angle between incident and reflection waves, and amplitudes for prestack time migration in angle-domain. A prestack time migration method and the work-flow that can generate imaging gathers in angle-domain are proposed. We do a numerical analysis of the effects of velocity gradient on travel time, angles, and amplitudes, and then propose angle and amplitude calculation methods that can treat media heterogeneity better. Numerical tests of model and real data demonstrate the effectiveness of the scheme. |
