d ray-tracing

基本解释

Based on Fermat's principle, the paper uses full-path iterative algorithm to realize 3-D VSP two-point ray tracing in volume element model.
本文基于费马原理，利用全路径迭代算法实现体元模型中的三维VSP两点射线追踪。
Ray tracing techniques are widely applied in seismology, among which the shortest path method (SPM) is robust for 3-D ray tracing in complex velocity structures.
射线追踪技术在地震学领域有着广泛的应用，其中以最短路径算法在复杂介质中走时计算稳定性最好。
The radome is considered as multilayer medium flat, the 3-D ray tracing method is used to build antenna-radome mathematical model for the radome electric performance computation.
结果表明这种方法可以用于电大尺寸波导裂缝阵天线一天线罩系统的电性能计算。
