摘要:
从理论研究和实验研究2个方面总结国内外有关大气中激光传输的研究进展,重点分析了降雨气象条件下对激光传输过程的影响。研究结果发现模拟仿真法在研究激光在大气中的传输时,一般采用常用的经验模型,该模型不具有普适性。雨场模拟实验中,设备产生的降雨在空间分布并完全不均匀,造成了两波段激光衰减系数实验值与理论值的误差。利用公式计算分析时,由于忽略了水汽吸收、雨滴散射等因素,从而使数据具有局限性。通过对理论模型仿真、模拟实验环境和数值计算与公式推导这3种实验方法的对比分析,提出了进一步改进有关降雨时激光通信实验研究的思路。
Abstract:
This paper summarizes the research progress in atmospheric laser transmission at home and abroad from two aspects of theoretical research and experimental research,analyzes the influencerainfall weather conditionson laser propagation.The results show that the simulation method in the study of laser propagation in the atmosphere,generally adopts the commonly used empirical model which is not universal.During the rain field simulation experiment,the spatial distribution of rainfall from the equipment is not uniform,resulting in error for the two band laser attenuation coefficient experimental and theoretical value.Using the formula for calculation and analysis,due to the neglect of the water vapor absorption and raindrops scattering factors,so that the data has limitations.Based on theoretical model simulation,simulation experimental environment and numerical calculation and formula,we have derived the contrast analysis of the three kinds of experimental methods,and proposed ideas for the further improvement of rainfall experimental study of laser communication.
