对复杂地形情况下实际湍流大气中的激光强度起伏进行了系统的实验观测，分析了光强起伏统计特征的周日及全年变化规律。结果发现:复杂地形情况下实际湍流大气中的激光光强起伏，不论是概率密度分布还是其功率谱等统计特征均与理论上的偏离很大。

A series of measurments of the irradiance scintillation of a He Ne laser beam propagating over complex terrain were carried out. The statistical properties of the irradiance scintillation, such as the scintillation index, probabitity distribution, and power spectrum were analysed. It was found that these statistical properties of the irradiance scintillation over complex terrain greatly deviate from the theoretic results.
