大气湍流对无线紫外光通信的影响
The effect of atmospheric turbulence on wireless ultraviolet communication
摘要
Abstract
In order to verify the effect of the atmospheric turbulence on the UV attenuation,ac-cording to the mathematical model of the refractive index structure constant,SNR,and the fa-ding probability,a comparative study was conducted.The analysis was made of the variation of refractive index structure constant with different height,SNR of the system and the attenua-tion of signal in different intensity of atmospheric turbulence.The results show that when the other conditions are the same,the wavelength is smaller and the SNR is higher.The moderate intensity of atmospheric turbulence(C 2n =10 -1 4 )effect on SNR is about 20dB lower than with-out.The stronger of turbulence and distance,the greater attenuation of the signal.The effect of turbulence on communication attenuation can be reduced by increasing the receiving aper-ture.关键词
