高能激光在实际大气中的传输是一个涉及到光传播机理、大气光学特性以及激光与大气相互作用的复杂过程,评估高能激光大气传输性能,不仅需要开展激光传输机理研究,建立高能激光大气传输数理模型,还需要对实际传输路径中的大气光学特性进行测量和分析。针对高能激光系统工程应用的迫切需求,简要介绍了高能激光大气传输性能评估研究的方法和发展现状,重点讨论了影响高能激光大气传输评估准确性的大气参数测量不确定性问题,指出了高能激光大气传输评估应重点关注的研究方法、测量的大气参数及评估技术发展的趋势。

The propagation of high energy laser in the real atmosphere is a complex process involving the mechanism of light propagation,the optical properties of atmosphere and the interaction between laser and atmosphere.To evaluate the propagating performance of high energy laser,it is necessary not only to study the mechanism of laser propagation to establish the mathematical model of high-energy laser propagation in atmosphere,but also to measure and analyze the optical properties of the atmosphere in the actual transmission path.In view of the urgent need of engineering application of high energy laser systems,the methods and development of the evaluation of high energy laser propagating performance in atmosphere are briefly introduced,with emphasis on the discussion of the uncertainty of atmospheric parameter measurement which affects the accuracy of high energy laser propagation in atmosphere.The research methods,the atmospheric parameters and the development trend of evaluation technology,which should be paid more attention to,are suggested.
