摘要
对大气湍流相干长度的统计特征进行了理论分析，给出了其概率分布密度函数，同时分析了光束大气传输湍流效应的远场斯特列尔（Ｓｔｒｅｈｌ）比的随机分布特征，得到了与实验非常一致的结果。
In this paper, the random fluctuation characteristics of the atmospheric turbulence coherence length and the light beam propagation far field strehl ratio are analysed and their probability density functions are derived based on the characteristic function of random variable. The theoretical analysis is validated by the experimental results.
