摘　　要：授时接收机通过接收并处理卫星导航信号以获取高精度时间,为通信、电力及金融等系统提供精准的标准时间信号。提出了一种针对授时接收机的转发式欺骗干扰技术,通过对目标接收机的精密定位以及转发信号的精确时延控制,实现了对授时接收机的定时偏差控制,从而使其上层系统无法正常工作。通过建立仿真模型,验证了该欺骗干扰技术的有效性。To supply accurate stand time signal, timing receivers were used to acquire high precision time by processing satellite navigation signals. A re-radiating spoofing technique was proposed, which dealt with the target receiver＇s timing uncertainty by controlling the signal delays and positioning antenna precisely. Once the timing receiver was controlled by the spoofing signals, the host system could be collapsed. Simulation results validate the effectiveness of the proposed spoofing technique.
