摘　　要：本文研究了转发欺骗干扰对卫星导航接收机载波跟踪环的影响。推导出在存在转发欺骗条件下卫星导航接收机载波跟踪环输出的相位误差公式,分析了不同强度的转发欺骗干扰对卫星导航接收机跟踪环路的作用,得出了使卫星导航接收机跟踪环路失锁转发欺骗干扰所需的最小功率强度。通过试验验证了本文分析结论的正确性。The effecting of spoofing signal on carrier loop of GNSS receiver was studied in this paper.The phase error formula of carrier loop was derivate with presence of spoofing signal.The effecting on the GNSS receiver loop with varied spoofing signal strengths were analyzed,and the minimum spoofing signal strength that could led missing lock of carrier loop is obtained.An experiment has been carried to validate the conclusions proposed in this paper.
