| 摘 要： | 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. |

| Abstract: | The characteristics of the wave propagation in hilly areas and the method of the point to point field-strength prediction are analyzed based on C++Builder and MapObject.First,the section from point to point is obtained based on the electric map,and then the loss of the empirical model and the specific model is given here.It is shown that the result of the specific model agrees with that of the ITU recommendation,and it is more precise than the empirical model. |
| Keywords: | field-strength prediction empirical model specific model |
