摘要

使用自由空间光学(FSO)的无线通信对大气条件很敏感。晴空乱流会造成严重的损害,降低FSO信道的可用性。利用罗马(意大利)和慕尼黑(德国)附近的辐射探测剖面,通过一种新的物理折射率结构常数模型来估计功率闪烁指数,并估计近红外FSO的闪烁衰减统计。对慕尼黑附近的地面链路和倾斜链路进行了FSO运动的初步定性验证。

Clear-air turbulence effects modeling on terrestrial and satellite free-space optical channels
Wireless communications using free space optics (FSO) are sensitive to atmospheric conditions. Clear-air turbulence can introduce severe impairments reducing FSO channel availability. Radiosounding profiles, available near Rome (Italy) and Munich (Germany), are used to estimate the power scintillation index through a new physical refractive index structure constant model and to estimate scintillation fade statistics for near-infrared FSO. Preliminary qualitative validation is performed using FSO campaign near Munich for both terrestrial and slant links.
