Abstract
An effective method to attack GNSS receivers tracking the authentic satellite is to make the code phase of spoofing signals relatively slipping respect to the corresponding authentic ones. In this paper, a detection technique based on ratio test of correlation peak is proposed to the auto-aligned synthesis spoofing mode. By analyzing the distortion process of correlation peak, the maximum of the ratio test result and its position are calculated, and setting the threshold of ratio test accordingly. Simulation results show that the proposed ratio test method could achieve a detection probability of 90 % with a false alarm probability of 5 %, and could also avoid false alarm induced by multipath and signal fluctuations.
