| 英文摘要 | Numerical simulation of acoustic wave equation is widely used to synthesize seismograms theoretically, and is also the basis of the reverse time migration. With some stability conditions, grid dispersion often exists because of the discretization of the time and the spatial derivatives in the wave equation. How to suppress the grid dispersion is therefore a key problem for finite difference approaches. Time-space domain methods using plane-wave theory and Taylor series expansion are proposed to suppress grid dispersion recently. However, these methods can only preserve the real wavefield in a small range of frequencies and angles of propagation. To suppress the grid dispersion further, we propose to satisfy the grid dispersion relationship in a range of frequencies and angles of propagation. Dispersion analysis and seismic numerical simulation demonstrate the effectiveness of the proposed method. |
