| 摘 要： | 电磁波在对流层中传播时,不可避免地要受到各种大气微粒的影响而产生衰减,而大气降水是引起电磁波衰减的最常见也是最主要的原因。大气降水有多种形式,主要为降雨、降雪、雾等。分析了各种降水形式的影响,从理论上进行了推理计算,并且给出了衰减率计算的方法,最后以图的形式直观地展示了大气降水对电磁波传播的衰减。

| Abstract: | When spreading abroad in the troposphere,it is hard to avoid that electromagnetic wave is reduced because of the influence of atmosphere mote,in which precipitation is the most familiar and the major element,including rain,snow,fog and so on. In this paper,influence of several ways of precipitation is analyzed,and is inferred by the way of theory. Expressions are solved to calculate the attenuation,and the attenuation of electromagnetic wave reduced by precipitation is showed in the way of graph. |
