摘　　要：在个人通信以及移动通信环境中,预测无线电波传播特性的常用技术是射线跟踪,射线跟踪在光散射特性计算中也有应用。文章基于射线方程和球表面方程实现射线端点和单球的计算距离算法,称为单球的求距离算法,多球的射线跟踪通过反复调用单球的求距离算法来实现,文章给出了多球射线跟踪仿真结果,从给出的结果可以看出,文章设计的算法能够实现多个球形粒子的射线跟踪仿真。In personal communication and mobile communication environments, the common technique for predicting the characteristics of radio wave propagation is ray tracing,which is also applied in the calculation of light scattering property. The algorithm for calculating the distance between ray endpoint and single ball is realized on the basis of the ray equation and the spherical surface equation,and it is called the single ball distance algorithm. Multi-ball ray tracing is achieved by repeatedly calling the single ball distance algorithm. The results of multi-ball ray tracing simulation are presented. The results shown in this paper indicates that the algorithm can realize the ray tracing simulation of multiple spherical particles.
