摘要
为改善红外光通信系统,研究雾霾天气对红外光通信信道容量的影响。在两个地区分别进行红外光通信链路的架设,在晴朗天气下对架设通信链路的红外光通信信道容量进行测量,并将该组数据作为对比组数据,在不同颗粒直径即不同浓度的雾霾天气下,通过实验设备获取架设的红外光通信链路的红外光通信信道容量,利用本端的激光大气通信机等设备进行伪随机序列码的发送,利用对端的红外光通信链路等设备对接收的伪随机序列码进行误码分析,通过误码分析结果计算红外光通信信道容量,将所得数据作为实验组数据,对比实验组数据与对比组数据,对雾霾天气对红外光通信信道容量的影响进行分析。根据分析结果可知,随着雾霾浓度的逐渐增加,红外光通信信道容量也随之逐渐减少,雾霾浓度与红外光通信信道容量呈反比状态。雾霾天气会导致红外光通信信道容量的减少,影响红外光通信。
In order to improve the infrared optical communication system,the influence of haze weather on the channel capacity of infrared optical communication is studied.Infrared optical communication links were erected in two areas respectively.The capacity of infrared optical communication channels erected with communication links was measured in sunny weather.And the data were used as a comparison group.Under different particle diameters or different concentrations of haze weather,the infrared optical communication channel capacity of the communication link was obtained through experimental equipment.The pseudo-random sequence code was sent through the end of the laser atmospheric communication equipment.The error analysis was received through infrared optical communication link at the end of the equipment.Through error analysis results,the infrared optical communication channel capacity was calculated,and the data obtained as for the experimental group data.The influence of haze weather on the capacity of infrared optical communication channel was analyzed by comparing the experimental group data with the control group data.According to the analysis results,with the increase of haze concentration,the capacity of infrared optical communication channel decreases gradually,and the concentration of haze is inversely proportional to the capacity of infrared optical communication channel.Fog and haze can reduce the capacity of infrared optical communication channel and affect infrared optical communication.
