摘　　要：在分析各种可能的欺骗干扰方法的基础上,研究了欺骗干扰信号的特性,并从信号体制设计和接收机信号处理两个不同层面提出了一系列通用的抗欺骗措施,可直接用于关键民用基础设施GNSS接收机的抗欺骗设计。Spoofing can conduct effective interference with lower power than normal interference method,and it will become to a main jamming mode to the satellite navigation systems.By re-radiating the target signals or generating similar spoofing signals,spoofing interference can make the receivers derive inaccurate PVT information,which may disrupt the critical national infrastructure such as the power supply systems and the wireless communication systems.By analyzing the spoofing interference methods and the signal characteristic,we propose a series of anti-spoofing techniques,which can be a reference to the anti-spoofing design of the GNSS receivers used in the key civil infrastructures.
