C波段大气闪烁特性研究

A Study on Atmosphere Scintillation Characteristics at C-Band

本文介绍了在中纬地区进行的长时间大气闪烁测量实验，分析了闪烁幅度分布规律及其时间特性；结合当地气象数据，讨论了闪烁和气象的关系；从闪烁频谱的分析看出在小幅度闪烁时频谱密度衰减系数与闪烁指数Ｓ４及地面温度有一定的相关性。

Abstract A long period experiment about atmosphere scintillation at middle latitude is introduced.The probability density tunction and time spectra characteristics of amplitude scintillation are analyzed.The relationship between edntillation and meteoroIOgical conditions are also discussed with the help of the local meteorological data.It isshown that spectral density attenuation coefficient has some correlation to scintillation index S, and the ground temperature at small amplitude scintillations.
