| 摘 要： | 到达角起伏是影响近地大气激光通信链路性能的最主要因素之一。文章对近地大气湍流信道中的激光束传输到达角起伏进行了计算和实验研究。研究结果表明，在大气折射率结构常数为10^-13～10^-16量级的范围内，根据Kolmogorov湍流理论，当大气信道满足局地均匀各向同性条件下，由理论分析和实验数据计算出到达角起伏的值，进而计算出的大气折射率结构常数值，与实验测得的大气折射率结构常数值是基本一致的。

| Abstract: | Angle-of-arrival fluctuation is one of the most primary factors affecting the performance of low-earth orbit laser communication link.Calculation and experiment of such fluctuation has been carried out in this paper in condition that the laser beam is transmitted in the channel of low-earth orbit atmospheric turbulence.This research indicates that when the atmospheric refractive index structural parameter is at the range of 10-13 to 10-16 orders of magnitude,and the atmospheric turbulence is locally uniform... |
