基于游戏引擎的电波传播可视化软件开发

摘要

为直观地研究城市区域的电波传播特性，自主开发了电波传播可视化软件。该软件基于专业游戏引擎Unity3d开发而成，支持三维射线跟踪建模方法，使用C语言编写的动态链接库（DLL）计算多径信息，采用C＃脚本实现可视化功能。该可视化软件适用于微蜂窝场景中的电波传播预测，支持场强、角度、时延、路径损耗等仿真数据的可视化。仿真结果表明该软件可为微蜂窝环境下的无线网络规划和优化提供直观、有效的参考。%In order to intuitively study the characteristics of radio propagation in urban area,we independently develop a visualised software for radio propagation.The software is developed based on the specialised game engine Unity3d.It supports 3D ray tracing modelling method and uses the dynamic link library (DLL)programmed by C language to calculate the parameters of multipath,and adopts C Sharp script to implement the visualisation function.The software is suitable for predicting the radio propagation in the micro cellular scenario, supports the visualisation of simulation data such as field strength,angle,time delay and path loss information.Simulation results indicate that the software can provide an intuitive and effective reference for wireless network planning and optimisation in microcellular.
