| 摘 要： | 对流层散射通信是一种重要的超视距通信手段,近几年大容量对流层散射通信已成为对流层散射通信的一个重要研究方向,飞行器衰落也是对流层散射通信研究的一个重要问题。在分析对流层散射通信信道的基础上,将对流层散射传播特性与飞行器前向散射传播特性作对比,重点分析飞行器导致的多径时延和多普勒频移变化。通过理论分析和仿真评估飞行器飞越对流层时散射通信信道特征,为探索克服飞行器衰落的关键技术提供了参考。

| Abstract: | Troposcatter communication is an important OTH(Over the Horizon) communication method.Recently,high rate digital troposcatter communication has become an advanced research direction,and aircraft fading is also an important issue.In this paper,based on an analysis of troposcatter communication channel,we make a comparison between the transmission characteristics of aircraft scatter and troposcatter,and analyze primarily the variation of multi-path delay and Doppler shift as a result of aircraft disturbance.W... |
