摘　　要：为了直观展示城市电波传播特性,设计一种电波传播特性可视化软件。宏蜂窝场景下,该软件基于地理信息数据,利用经验模型,实现了单基站、单频网和多频网的覆盖分析;微蜂窝场景下,该软件结合开放图形库(OpenGL),利用三维射线跟踪模型,实现了场强、时延、角度等电波传播特性参数的可视化。应用结果表明,该软件便利了信息统计特性的获取,可为无线网络规划提供直观、有效的参考。In order to directly demonstrate the radio propagation characteristics of urban environments, we design the software of radio propagation characteristics visualisation. On macrocell scenarios and based on geographic information data, the software utilises the empirical model to realise coverage analysis of single base station, single frequency network and multiple frequency network ; On microcell scenarios and in combination with open graphic library （ OpenGL）, the software uses 3D ray tracing model to achieve the visualisation of radio propagation characteristic parameters such as the field strength, time delay and angle information, et al. Applications results show that this software facilitates the acquisition of information statistic characteristic, and can provide an intuitive and effective reference for the wireless network planning.
