基于多跳HF的海上船舶通信时长研究

本文研究使用多跳高频无线电波进行通信的海上船舶可以保持通信的时间。首先,分析信号从陆地点源发射到海上船舶接收器这个过程中包含的信号衰减。从接收天线增益的角度,结合天线仰角和方位角的变化,着重分析了由于船舶的晃动引起的信号不完全接收,并将其折算到信号在海面上的漫反射损耗。最后,将模型应用于实际背景,计算了船舶在海上的通信时长。

In this paper,the time of communication for a marine vessel in which a multi-hop high-frequency radio wave is used for communication can be studied.First,the signal attenuation included in the process of transmitting the signal number from a land point source to a marine vessel receiver is analyzed.From the angle of receiving antenna gain,combined with the change of antenna elevation and azimuth angle,the incomplete reception of signal caused by ship’s sloshing is analyzed and converted to the diffuse reflection loss of signal on the sea surface.Finally,the model is applied to the actual background,and the communication time of the ship at sea is calculated.
