摘要
介绍了北斗卫星导航系统组成、信号特点及其应用领域,然后指出北斗卫星导航信号的宜被干扰性,概述了目前主要采用的干扰与抗干扰技术,最后提出应从国家安全层面认识北斗卫星导航的抗干扰问题。
This paper introduces the composition, signal characteristics and application fields of compass navigation satellite system. Considering that the compass navigation satellite signals are easy to be jammed, major jamming and anti-jamming tech- niques are outlined. It proposes that compass navigation satellite systems＂ anti-jamming problems should be understood at the level of national security.
