Guangwei Fan, Zhenhua Wang · Advances in engineering research/Advances in Engineering Research · 2015
Concerning the problem that a single spoofing detection method has poor performance in the receiver capturing phase, this paper presents a joint spoofing detection algorithm that combines the signal arrival time detection with the capturing correlation peak detection.The relationship among detection probability, false alarm probability and detection threshold is derived in addition to an analysis to the performance and the scope of application of the proposed method.It solves the problem of failure to detect repeater spoofing and strong generator spoofing interferences simultaneously in the receiver capturing phase.The algorithm has good application prospects, for it does not require additional equipment to the existing receivers in addition to low computation complexity.
