在C++Builder和MapObject的平台之下,详细分析了在丘陵地区无线电波传播的特点以及点到点的场强预测方法。首先根据电子地图求得点到点的剖面图,之后在此基础上分别计算了在经验模型之下和确定模型之下的损耗结果,最后对比得出结论:确定模型与ITU(International Telecommunication Union)建议的模型计算出的结果比较一致,均比统计模型更加精确。
Under the platform of C ++ Builder and MapObject, the characteristics of radio wave propagation in hilly area and the field strength prediction method from point to point are analyzed in detail. First, the point-to-point profile is obtained from the electronic map, and then the loss results under the empirical model and the deterministic model are respectively calculated. Finally, the conclusion is drawn that the model and ITU (International Telecommunication Union) The results of the model are more consistent and more accurate than the statistical model.
