摘要
非均匀对流层对投射的电磁波会产生二次辐射,从而进行前向散射,形成超视距传播。文中介绍了对流层散射的传播原理、对流层的几种数学模型,对流层散射的各种损耗,以及基于对流层散射传播原理的微波超视距无源探测定位系统的探测性能分析,给出了探测距离R与工作频率f的关系曲线和探测距离R与辐射源功率P的关系曲线。
The non-homogenous troposphere can radiate radio wave and forward disperse,and come into being over-the-horizontal propagation.Firstly,the propagation principle of tropospheric dispersion is introduce,some of mathematics model of the troposphere is also introduced in this paper.And then,each of troposphere dispersion loss is given.Finally,the exploration capability of the microwave over-the-horizontal system based on the propagation principle of tropospheric dispersion is analyzed,the curves between exploration range R and work frequency f and between exploration range R and radiant power P are given.
