摘要
利用统一基准的光波传输特性综合测试设备,测量了北京和成都两个测试点在降雨天气下的常见大气效应,包括大气衰减、光强闪烁、达到角起伏、光斑漂移和光束扩展等。综合测试数据进行分析整理,得出城市环境条件下雨天无线光信道特性。
Based on the synthetic test instrument for the characteristics of optical wave propagation with uni- fied datum, this paper acquires the data about common atmospheric effects in Beijing and Chengdu, the com- mon atmospheric effects include atmospheric attenuation, irradiance scintillation, angle-of-arrivalfluctuation, beam wander and beam spreading. Through testing and analyzing the data, the paper gives the communication channel characteristics on optical wireless with rainfall in urban area.
