摘要
分析近距短波无盲区通信的电波传播方式及性能,对指导工程实践具有重要的意义。在现有研究成果的基础上,总结了陆地地面近距短波通信电波传播仿真计算模型,论述了相关参数的计算取值,针对某在用系统的近距短波通信网,对地波和天波传播进行了Matlab仿真计算及对比分析,得出了较实用的结论。
In the engineering applications of short-range HF no-blind zone communication,analyzing the propagation modes and characteristics of electromagnetic wave plays guidance role to engineering practice.Based on the studies so far,we summarize the simulation computation models of electromagnetic wave in short-range HF no-blind zone communication on the ground,and discuss the calculation of relevant parameters.We also simulate the ground-wave and the sky-wave propagation of short-range HF communication network with certainparameters in Matlab, and then compare the results to draw a practical conclusion.
