| 摘 要： | 对求出的射线路径进行整体优化，以减小离散化所产生的误差，从而减小射线路径的误差。对射线路径优化过程进行了推导，并提出了最短射线路径的优化循环迭代算法，求出了优化的最短射线路径。应用理论模型验证了最短射线路径的优化循环迭代算法的可行性；相对于理论路径而言，优化最短射线路径法得到的射线路径误差较小。将该方法应用于最短射线路径追踪和折射波静校正等资料处理的过程中，可以减少运算量和运算时间。 |

| Abstract: | The calculated ray paths are optimized overall so as to reduce the errors resulted from the discretization and to reduce the errors of ray paths. Process of optimized ray paths is derived. The optimized cycling alternation algorithm for the shortest ray path is brought forward and the optimized shortest ray path is given. Theoretical model is applied to proving the feasibility of the algorithm. Compared with the theoretical path, the error of the ray path got by the optimized shortest ray path tracing method is minimum. The method can be applied in the shortest ray path tracing and the processing courses such as refraction wave static correction and can reduce the operating quantity and time. |
| Keywords: | shortest raypath travel time discretization overall optimized algorithm |
