摘要/Abstract

摘要： 微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。本文研究水的介电常数的物理特性，应用Mie理论和常用的Laws-Parsons雨滴分布模型，利用Matlab软件仿真分析电磁波衰减随降雨率变化的关系；综合考虑降雨对微波吸收和散射的影响，通过对雷达信噪比计算得出降雨的衰减量。

关键词: 电磁波衰减, Mie理论, 降雨吸收

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 is rain. Some research is done on the physical character of dielectric constant of water. Using the Matlab, Mie theory and the Laws-Parsons model of rain distribution are used to analyze the relationship of electromagnetic wave attenuation with rainfall change. The infection on absorption and dispersion of electromagnetic wave is considered. The attenuation of rainfall is educed by the calculation of signal-to-noise.

Key words: electromagnetic wave attenuation, Mie theory, rainfall absorption
