基于射线追踪法的电波特性研究

根据几何光学和统一绕射理论城市微蜂窝通信中的信号传播模型,使用射线跟踪技术,考虑了跟踪过程中射线在墙面和地面的反射及射线在建筑物拐角处的绕射。对某小区的电波传播特性进行计算,分析不同区域的路径损耗。

Research of Wave Propagation Base on Ray Tracing Method

Based on Geometry Optical Theory and Uniform Theory of Diffraction,this paper put forward signal propagation model in urban microcellular communications,in this paper,it uses ray tracing method and takes into consideration the reflection from the ground and building walls,diffraction from corners.Adopting the method mentioned above,we analysis different district exhausts.
