| 摘 要： | 基于ITU-R P.526-11建议书中的电波传播模型,将传播路径上的地形遮挡视为单仞峰,主要考虑自由空间传播和地形绕射带来的传输损耗,基于数字高程模型提供的地理信息数据,预测了用于地空通信的地面通信站覆盖范围,一定程度上可以辅助进行地面通信站的选址;在地面站实际使用过程中,依据预测的覆盖范围,可以让使用人员对通信的通断心中有底。

| Abstract: | According to P.526-11 wave spread model recommend by ITU-R and basing on digital elevation model,coverage that is effected by terrain of ground communication station deployed at certain position is predicated.During that terrain obstacle is concerned as a single blade,coverage prediction is helpful to deploy communication station and be sure of communication. |
