In this paper,a method for spoofing detection based on the variation of the signal's carrier-to-noise ratio(CNR)is pro-posed.This method leverages the directionality of the antenna to induce varying gain changes in the signals across different inci-dent directions,resulting in distinct CNR variations for each sig-nal.A model is developed to calculate the variation value of the signal CNR based on the antenna gain pattern.This model enables the differentiation of the variation values of the CNR for authentic satellite signals and spoofing signals,thereby facilitat-ing spoofing detection.The proposed method is capable of detecting spoofing signals with power and CNR similar to those of authentic satellite signals.The accuracy of the signal CNR variation value calculation model and the effectiveness of the spoofing detection method are verified through a series of experiments.In addition,the proposed spoofing detection method works not only for a single spoofing source but also for distributed spoofing sources.
