摘要
随着科学技术的发展,空间电磁场环境越来越复杂,卫星导航终端也面临越来越多的干扰源,其中包括卫星导航信号本身频率的带内干扰和北斗卫星导航系统卫星无线电测定业务(Radio-Determination Satellite Service,RDSS)发射信号对接收通道的干扰。现针对导航信号的带内干扰模式分析射频通道的关键指标,以备后续应用开发作参考。
With the development of science and technology,the space electromagnetic field environment has become more and more complex,and satellite navigation terminals are also facing more and more interference sources,including in-band interference of the satellite navigation signal's own frequency and the satellite radio determination service of Beidou satellite navigation system Radio-Determination Satellite Service(RDSS)the interference of the transmitted signal to the receiving channel.Now,the key indicators of the RF channel are analyzed for the in-band interference mode of the navigation signal for reference in subsequent application development..
