摘要
为了克服大气湍流效应对无线光通信系统性能的影响,必须建立能准确描述大气折射率起伏的湍流模型。总结了国内外学者在大气湍流模型方面的研究进展,对不同大气湍流模型的理论建立进行深入分析并对比了其适用范围,同时介绍了在实际大气湍流中实验测量所建立的大气信道模型,最后对大气湍流模型的发展趋势进行了展望。
In order to overcome the influence of atmospheric turbulence effect on the performance of wireless optical communication system,it is necessary to establish a turbulence model which can accurately describe the fluctuations of atmospheric refractive index.This paper summarizes the research progress of atmospheric turbulence models at home and abroad,analyzes the theoretical establishment of different atmospheric turbulence models in depth and compares their application ranges.At the same time,the channel model of atmospheric established in the actual atmospheric turbulence measurement is introduced.Finally,the development trend of atmospheric turbulence model is forecasted.
