摘要
为了保证光通信精确度,有效地提高光通信系统性能,分析了导致接收光束能量损失,接收信号减弱的成因,找到适合光通信的方法.首先,通过光通信对大气信道衰减的敏感性,分析了光通信在大气传输时所受到的大气环境如雾、雨、雪、大气湍流因素的影响.其次,对大气环境中的雾、雨、雪和大气湍流中光强起伏、光束漂移等因素对光通信的影响做了详细分析.最后,通过数据分析得出适合光通信的大气环境,在合理使用大气激光通信设备的前提下,可以保证光通信的质量.
In order to ensure the accuracy and improve the performance of optical communication system,the causes of the receiving beam energy loses and the receiving signal weakens when optical communication happens were analyzed,and a suitable way was proposed.First,by the sensitivity of optical communication to the atmospheric channel attenuation,four factors from atmospheric environment including fog,rain,snow and atmospheric turbulence were analyzed.Second,the effect of intensity fluctuation and beam drift in the fog,rain,snow and atmospheric turbulence on the optical communication were discussed.Finally,through the analysis of the data,the suitable atmospheric environment for optical communication was obtained and the quality of optical communication can be ensured on the premise of the rational use of atmospheric laser communication equipment.
