摘要
开展了传输距离500 m复杂地形下的激光大气闪烁与衰减的同步实验观测?讨论分析了闪烁强度、概率分布和频谱等特征量随透过率变化的趋势,发现大气闪烁和消光之间有一定的关系。
Abstract
It is carried out a series of synchronous measurnients of the irradiance scintillation and the extiction of a He-Ne laser beam propagating through a real turbulent atmosphere over complex terrain. The relationship between the statistical properties of the irradiance scintillation, such as the scintillation index, the probability distribution and the power spectrum, and the extinction was analysed. There is certain relationship between laser irradiance scintillation and irradiance extinction in a real atmosphere.
