摘　　要：介绍电磁波在大气中传播的一种异常现象——"大气波导"现象,论述了大气波导形成的气象条件,以及形成波导传播的电磁波的最大陷获波长和临界发射仰角,同时论述了电磁波受大气波导影响能够增大舰载雷达的探测距离,实现舰载雷达的超视距探测及军事应用意义。The atmospheric duct,one kind of anomalous propagation in the atmosphere,is introduced in this paper.The atmospheric condition,the maximum trapped-wavelength and critical emitting angle of elevation for electromagnetic wave to form duct propagation is also derived in the paper.The atmospheric duct can make the radar increase detecting range to realize the phenomenon of OTH detection,so it is very important in military operation.

关 键 词：大气波导 超视距 探测距离
