【摘要】 北极东北航道处于高纬度地带,卫星通信无法覆盖,船岸通信主要采用短波通信技术。本文通过仿真计算北极滨海区域海水的电导率与相对复介电常数,研究通信链路中海洋表面反射损耗与船舶接收信号的信噪比,并结合北极东北航道路线特点,优化设计北极东北航道短波通信链路。更多还原

【Abstract】 The Arctic northeastern sea-route is at high latitudes, and satellite communications cannot cover it. The ship-shore communication of arctic northeastern sea-route is mainly based on shortwave communication technology.In this paper, we calculated the conductivity and relative permittivity of seawater in Arctic coastal region by simulation, studied the reflection loss of the ocean surface and the SNR of the ship receiving signal. Concerning the characteristics of the northeastern route, we optimize the design of communication links in the Arctic northeastern sea-route.更多还原
