Research on one-key communication technology of Troposcatter communication based on Beidou

基于北斗的定位定向和位置信息交互机制实现散射通信两端的初始方位对准,适用于散射信号的信号捕获方法用于接收信号的搜索,通过检测衰落信道条件下接收信号中值进行天线角度的细对准,从而精准确定最佳信号接收角度,设计对控信令实现天线自动对准、信令波形至业务波形的无缝切换,无需人工操作。该技术方案经济实用,进行了多次试验验证,均取得了良好的通信效果和用户体验。

The technologies and implementations of one-key communication in troposcatter communication system are mainly studied in this paper.The location and orientation and the interaction mechanism based on beidou is designed to realize initial azimuth alignment at both ends of troposcatter communication.A signal acquisition method for troposcatter signals is designed to search for re⁃ceived signals.The antenna angle is precise aligned by detecting the median of the received signals in fading channel,to accurately determine the best signal receiving angle.Control signals are designed to realize automatic antenna alignment and seamless switching between signaling waveform and service waveform without manual operation.The technical scheme is economical and practical,and has been tested for many times.Good communication effect and user experience have been achieved.
