摘要
本文选用合理的模型模拟了大气信道中雨滴、烟雾带来的相干带宽,并进行了数值计算。结果表明:对于雨滴、轻雾信道,相干带宽很宽;而对于烟雾浓度较大的信道,信道的相干带宽应引起激光大气通信的重视。
The coherent bandwidths for laser atmospheric communication channels
through raindrops and fog are calculated in a reasonable mode. Some numerical
calculations are given. Calculating results show that the coherent bandwidths of
channels through raindrops and fog are very wide, but the coherent bandwidths
should be considered in the case of laser atmospheric communication channels
through thick fog.
