| 摘要: |
| 随着全球导航卫星系统的广泛应用，其安全性问题也逐渐成为人们关注的焦点。为了对目前最具隐蔽性的诱导式欺骗技术进行检测，提出一种对两路导航信号同时进行处理的combo-signal模型，并提出基于这种信号处理模型来对诱导式欺骗信号进行检测的方法;分析了该方法的检测门限;采用北斗的B1I 和B1C信号在实现了combo-signal处理模型的软件接收机上对该检测方法进行了验证，实验结果证明该方法可以有效地对诱导式欺骗进行检测，统计得到的检测概率跟前面的分析结果一致。 |

| Abstract: |
| With the wide applications of the global navigation satellite system, the security problem of it has gradually become the focus of attention. In order to detect the induced spoofing, the most covert spoofing technology for satellite navigation systems, a combo-signal model which processes two satellite navigation signals simultaneously was proposed. Based on this signal-processing model, a method to detect induced spoofing signals was proposed. Then the detection threshold of the method was analyzed. An experiment with the BeiDou B1I and B1C signals and a software receiver implementing this combo-signal model was used to verify this method. The experimental results show that this method can effectively detect the induced spoofing. The statistics of the detection probability are consistent with the analysis. |
