本文建立了一种有效的基于射线跟踪技术的三维城市微区电波传播预测的计算模型.该模型将计算机图形学中的八叉树分区技术扩展至射线跟踪技术

并由此提出了一种新的有效的射线跟踪算法

射线跟踪八叉树算法.并基于几何光学、一致性绕射(UTD)对场强进行计算

所得结果与实测值及FDTD的结果进行了比较.

This paper presents a three-dimensional propagation model for path-loss prediction in an urban microcell

based on ray-tracing techniques.A new efficient ray-tracing technique based octree technique

which was used in computer graphics before

is presented.Numerical results based GO/UTD for received power are in agreement with the measured data and that predicted by FDTD.
