北斗卫星授时信号欺骗干扰检测技术研究

Research on the Detection Technology of Deception Interference of BeiDou Satellite Time Service Signal

电力系统中电能的生产、输送、分配以及使用是同时进行的,这就需要有统一的时间基准来满足电力系统安全稳定判别、经济调度运行以及事故反演分析等需要,因此依靠北斗精准授时的时间同步系统的精准可靠尤为关键。对此,阐述了卫星授时信号的干扰分类,针对欺骗干扰的特征提出了检测手段,为实现欺骗干扰信号的感知与智能化防御提供理论依据。

The production,transmission,distribution and use of electric energy in the power system are carried out at the same time,which requires a unified time benchmark to meet the needs of power system security and stability discrimination,economic dispatching operation and accident inversion analysis.Therefore,the accuracy and reliability of the time synchronization system relying on BeiDou precise timing is particularly critical.In this regard,this paper describes the interference classification of satellite time service signal,and puts forward detection methods according to the characteristics of deception interference,which provides theoretical basis for realizing the perception and intelligent defense of deception interference signal.
