倾斜地面对短波天线通信的影响

摘要

This paper is focused on the influence of communications of short wave antennas set up on the sloping ground.Discussion of the relationship between antenna height and elevation angle as well as gradient of terrain is given.Also analysis on influence of the size of the smallest Fresnel zone by different gradient of terrain is pointed out.%文章将研究在通信方向上倾斜的下坡地形对短波天线通信的影响。讨论了天线架高随通信仰角和地形坡度的关系;分析了在不同的倾斜角度下的地形对最小菲涅尔区的尺寸的影响。
