基于模拟退火法的弯曲射线追踪

提出了一种新的射线追踪方法——模拟退火法.新方法不仅较好地解决了传统射线追踪方法过分依赖初始模型的问题,而且对于复杂速度场模型也能保证在固定的发射与接收点之间构建令人满意的射线路径及其相应的走时,搜索到满足旅行时全局最小的射线路径.此外,新方法还可计算局部最小旅行时,并可方便地通过指定射线经过固定点来对射线路径进行限制...

BENDING RAY-TRACING BASED ON SIMULATED ANNEALING METHOD

This paper proposes a new ray-tracing method based on the concept of simulated annealing.With the new method,not only the problem that the traditional ray-tracing method is over dependent on pre-established initial ray-paths is well solved,but also the quality of desirable ray-paths construction and the associated traveltime calculation between fixed sources and receivers is ensured,even if the model is of much complicated velocity-field.As a result,the ray-paths whose traveltime approach is overall minimum...
