摘　　要：针对近海环境对船舶无线通信系统稳定性和信号覆盖的影响,开展了近海水域船舶无线信道测量、分析与仿真研究。通过采集典型近海区域的无线信道数据,提取了信道特性,建立了近海船舶通信的信道模型,并对不同传播路径损耗模型的适用性进行了对比分析。分析了船舶无线信道的小尺度衰落特性。利用射线追踪技术对近海水域船舶无线信道进行了仿真研究。结果表明,近海水域船舶与水面对无线信道特性造成明显影响,圆形地球损耗模型可以更好地表征近海水域无线传播路径损耗特性。所开展的研究可以为优化近海船舶无线通信系统设计提供理论支持。This study investigates the impact of offshore environments on the stability and signal coverage of maritime wireless communication systems by conducting measurement,analysis,and simulation of wireless channels in offshore waters.Wireless channel data are collected from typical offshore regions to extract channel characteristics and establish a channel model for maritime communication.A comparative analysis of the applicability of various path loss models is performed,along with an examination of small-scale fading characteristics in maritime wireless channels.Additionally,ray tracing techniques are used to simulate wireless channels in offshore waters.The results demonstrate that vessels and water surfaces in offshore environments significantly influence wireless channel characteristics,with the spherical earth path loss model providing a more accurate representation of path loss in offshore wireless propagation.This research provides theoretical support for optimizing the design of wireless communication systems for offshore vessels.
