| 摘要: |
| 电波在以视距传播方式进行传播时,在低空大气层中还要受到地面的影响。文中具体分析了视距传播下几种传播模型中地面起伏对电波传播衰减中值的影响,并进行了相应的计算,最后给出相应地面起伏度与传播衰减中值之间的关系。 |

| Effect of the Roughness of the Ground-surface on the Line-of-sight Propagation |
|
| () |
| Abstract: |
| The ultra-short wave and microwave propagation over the line-of-sight ground path is effected by roughness of the ground-surface .This paper analyses the reason that the roughness of the ground-surface effects the propagation over the line-of-sight.Finally it concludes the relation between the roughness of ground-surface and propagation attenuation. |
| Key words: Propagation,Line-of-sight propagation,Fresnel zone,Interfernce attenuation,Diffraction attenuation, |
