摘　　要：北极航道是指穿过北冰洋,连接大西洋和太平洋的海上航道,北极航道的快速发展对世界政治经济格局将产生深远影响。现有极区单台站短波通信易受极区恶劣空间环境因素的影响,可通率不高,无法对北极航道船舶的安全航行提供可靠保障。本文针对北极航道短波通信保障需求,搭建基于确定性模型的短波通信覆盖区评估理论框架,探究复折射指数射线追踪功率计算方法,进而评估北极航道短波组网通信效应,同时开展了高能粒子沉降等极区电离层扰动对北极航道短波传播效应影响的研究,旨在为短波组网北极航道通信效能评估与站网规划设计提供理论基础。Arctic shipping routes connecting the Atlantic and Pacific Oceans through the Arctic Ocean,are rapidly evolving and will have profound implications for global geopolitics and the economy.Existing single-station HF signal communication systems are vulnerable to the challenging polar space environment,resulting in limited reliability and an inability to ensure safe navigation of vessels along the Arctic shipping routes.In response to the communication needs of the Arctic shipping routes,we established a theoretical framework to evaluate HF signal communication coverage based on deterministic models.Furthermore,the calculation methods for power in complex refractive index ray tracing have been focused on.We evaluated the commu-nication effects of HF signal networking along the Arctic shipping routes,and investigated the impact of polar ionospheric disturbances,such as high-energy particle deposition,on HF signal propagation effects in polar region.This study provides a solid theoretical basis to assess the communication effectiveness of HF signal access networks and to optimize the design of station networks for communication along Arctic ship-ping routes.
