摘要
综述了复杂地形条件下激光大气闪烁效应的实验及理论研究结果,包括实验数据处理方法、闪烁概率分布的极大似然模型、闪烁频谱特征系统分析方法、小波变换频谱分析方法、光波起伏频谱与湍流谱的关系,以及闪烁的间歇性等统计特征.
Theoretical and experimental results on the scintillation effect of laser beam propagation through turbulent atmosphere over a complicated terrain are summarized. Main results include the processing technique of the experimental data, a maximum likelihood model for the scintillation probability, a systematical procedure for analyzing the scintillation temporal spectrum, a wavelet spectrum evaluation, the relationship between the wave spectrum and the turbulence spectrum, and the intermittency characteristics of the scintillation.
