摘要
地形是影响电磁波地表传播的重要因素,地形反射波对接收机天线的镜面效应直接影响相关电磁发射接收系统的电磁兼容性,甚至造成系统无法正常工作。通过对地表反射波产生镜面效应的原理进行分析,建立了天线藕合单向链路传播通道反射波地表镜面效应点分析判断模型,并对其应用进行了探索研究。
Terrain is an important factor which affects the electromagnetic transmission, the mirror effect of the terrain echo wave to receiving antenna affects the electromagnetic compatibility of system directly, indeedly leads to the paralysis of system. The paper analyzed the theory of the mirror effect, built an analyst and estimating model of the echo wave mirror effect in coincidence and unilateralism transmission alleyway and made research in the application of the model.
