舰船舱室环境下电波传播特性的仿真和分析

Simulation and Analysis of Radio Wave Propagation Characteristics in Ship Cabin

大型舰船的设计特点多具有封闭性,舱室内部空间空间结构复杂。舱室环境下无线信道的特征直接关系到无线通信质量。基于射线跟踪法,利用Wireless Insite计算软件平台对典型舰船舱室走廊环境下电波传播特性进行了建模,得出了在不同频段下的接收功率和时延扩展参数。经过比较分析得出了频段和空间因素对无线信道特性的主要影响,可以为舰船内部无线通信网络覆盖和基站规划设计提供指导。

Most of large ships are designed to be closed,and interior space structure of the cabin is complex.The characteristics of wireless channels in cabin environment are directly related to the quality of wireless communication.Based on the ray tracing method,the radio wave propagation characteristics in typical ship cabin corridor environment are modeled by using the Wireless Insite computing software platform,and the receiving power and delay spread parameters are obtained under different frequency bands.Through comparative analysis,the main influence of frequency and spatial factors on the characteristics of wireless channel is obtained,which can provide guidance for the design of wireless communication network coverage and base station.
