摘要
激光传输特性的研究可以为光电探测和通信系统的性能提供依据。采用后向散射式能见度测量仪测量后向散射回波能量,经过计算得出激光在大气中传播的消光系数。对不同能见度和天气条件下激光消光系数进行大量试验测量,得出统计规律,并与理论相比较,结果相符。
The research of laser transmission characteristic provides foundation for photoelectric detection and communication system. The backscatter energy is measured in backscatter visibility measuring set, and the extinction coefficient is calculated. The extinction coefficients under different visibilities and different weather environments are obtained by lots of experiments; and the statistical regularity is also obtained, and the results agree with the theory.
