大气波导的研究现状与思考

Research status and thinking of atmospheric duct

大气波导是一种可以实现超短波、微波频段超视距远距离传播的特殊超折射大气层状结构.文中对大气波导的研究现状进行了综合论述,重点包括大气波导的探测方法研究、机理分析和诊断方法研究、预报方法研究、传播评估和应用研究几方面的介绍,同时对大气波导各个方面的研究现状进行了一些思考,并给出了一些发展方向建议.目前大气波导的准确探测尤其是区域和水平不均匀性探测还很薄弱,机理研究和诊断、预报研究远远不能满足信息系统实际应用的需求,研究已经遇到瓶颈,亟待发展和突破.同时文中也指出了大气波导对电子信息系统是有利有弊的,在大气波导应用方面要"扬长避短",在对大气波导规律研究透彻的基础上,给出利用方案和防范方案,更好地为人类服务.

Atmospheric duct is a kind of special atmospheric structure with super refraction,which can realize the long-distance propagation of ultra short wave and microwave band.In this paper,the research status of atmospheric duct is comprehensively discussed,including the detection method research,mechanism research,prediction and prediction method research,propagation evaluation and application of atmospheric duct.At the same time,the research status of various aspects of atmospheric duct is considered,and some development direction suggestions are given.At present,to accurately detect atmospheric duct,especially the regional and horizontal inhomogeneity,is still challenging.The research on its mechanism and prediction can not meet the needs of the practical application of information system,thus it has met the bottleneck and needs to be developed and broken through urgently.At the same time,this paper also points out that the atmospheric duct has advantages and disadvantages for electronic information system,so we should"make good use of its advantages and avoid the disadvantages"in the application of atmospheric duct.On the basis of thorough research on the law of atmospheric duct,the utilization scheme and prevention scheme are given to better serve human beings.
