| 摘 要： | 对层状介质模型中的多分量波场传播进行简单分析及某些简化后,提出了三分量记录合成的快速近似算法。该算法使用射线追踪计算传播时间,应用波场界面方程计算反射振幅。由于采用了快速射线追踪算法及一些有效的简化,使该算法计算速度很快,一般模型在 AST 386微机上生成三分量记录仅需十几分钟至数十分钟。

| Abstract: | A fast simplified algorithm for generating three component seis- mogram is developed after simple analysis and some simplification of the propagation of multi-component wave field in layered medium model.This algorithm uses ray tracing to calculate traveltime,and de- rives reflection amplitude from wave field interface equation.The use of fast ray tracing and effective simplification speeds up the operation of this algorithm,so that generating three-component seis- mogram by AST 386 personal computer only takes ten minutes to several tens of minutes. |
