|
摘要
为研究电离层变化规律对岸舰短波通信电波传播的影响,直观展示在特定时间和地点通信发射机电波传播和通信畅通情况。基于工程中常见的电离层模型介绍了电离层参数和反射高度的计算方法,提出了岸舰通信电波传播距离计算模型、采样和可视化方法。通过仿真,可以得出电磁波以一定频率和入射角时传播时的通信畅通范围,也为短波电台通信频率选择提供方法。
In order to study the influence of the ionospheric law on the propagation of short wave communication waves on shore-ship,it is intuitive to show the communication of radio waves and communication at a specific time and place. Ionosphere parameters and reflection height calculation methods are introduced based on the common ionospheric model in the project. The propagation distance calculation model,sampling,and visualization methods for shore-ship communications are proposed. Through simulation,it is possible to obtain the communication open range at a certain frequency and the incident angle of the electromagnetic wave,and provides a method for the selection of the shortwave radio communication frequency.
