摘要：

In this paper, the multi-peak and power cooperative detection algorithm is proposed to detect forwarded spoofing interference signals of satellite navigation BOC modulation receivers without considering suppression interference. The theoretical value and the simulation value of the ROC curve of the multi-peak and power cooperative detection algorithm can be obtained by the numerical calculation and the experimental simulation. It can be seen from the simulation that with the increase of the number of accumulations after the receiver correlation value and the power intensity of the spoofing signal relative to the real signal, the detection probability of the proposed algorithm is higher. When the power of the spoofing signal is 3 dB greater than that of the real signal, the detection probability can be more than 90% under the condition that the false alarm probability is 5%. While when the power of the spoofing signal is 4 dB greater than that of the real signal, the detection probability can be more than 95% under the condition that the false alarm probability is 0.7%. Given that it only needs to add the module to the software receiver to detect spoofing signals, the algorithm proposed in this paper is of practical significance.
