摘要

针对2018年6月2日黄海部分海域船载AIS超视距通信受大气风道影响的现象，利用当时测得的大气温湿度廓线计算大气风道。根据计算得到的大气风道环境，采用抛物型数值方程模型和AIS覆盖评估模型对AIS在大气风道环境中的最大距离进行了分析。结果表明，该方法可用于评价AIS和其他超短波设备在大气管道等复杂折射环境条件下的最大距离。同时，通过AIS的超视距通信距离可以推断出大气风道的特性。

Analysis of Ultra-short Wave Propagation in Atmospheric Duct

Aiming at the phenomenon of Ship-borne AIS over-the-horizon communication in some area in the Yellow Sea in June 2, 2018, which influenced by atmospheric duct, the atmospheric duct is calculated by using the atmospheric temperature and humidity profiles measured at that time. According to the calculated atmospheric duct environment, the parabolic numerical equation model and the AIS coverage evaluation model are used to analyze the maximum distance of AIS in the atmospheric duct environment. The results show that this method can be used to evaluate the maximum range of AIS and other ultra-short wave equipment under complex refraction environment conditions such as atmospheric duct. Meanwhile, it also shows that the characteristics of atmospheric duct can be inferred based on over-the-horizon communication distance of AIS.
