摘要
对光强闪烁激光雷达在湍流大气中的双程光路传输路径进行了研究,分别得到了单站和双站情况下接收端获取的残余闪烁指数的表达形式。在大孔径条件下,双程光路的残余闪烁指数为发射光路湍流效应引起的球面波闪烁指数。通过光强闪烁激光雷达与闪烁仪的水平对比实验,理论结果得到了验证。
Abstract
Double-pass propagation path of residual turbulence scintillation lidar in turbulent atmosphere is studied and the expression forms of residual scintillation index acquired at the receiving terminal are obtained under the monostatic and bistatic cases, respectively. Under the condition of large aperture, the scintillation index of double-pass path is just scintillation index of spherical wave caused by the uplink path turbulence effect. By an experiment of horizontal comparison between residual turbulence scintillation lidar and scintillometer, the theoretical results are verified.
