With the development of GPS spoofer techniques,spoofing signals can be consistent with the authentic signals on direction of arrival (DOA) or pseudorange.The receiver will not be effective for detecting such spoofing signals,when using traditional spoofing detection method based on either DOA or pseudorange.In order to suppress this problem,a method based on the joint weighted sum of squares of errors (WSSE) of DOA and pseudorange for GPS spoofing detection is introduced.This method uses the carrier phase difference and pseudorange observations to form two equations simultaneously,and adds the residuals of two equations after normalization.According to the joint WSSE,it can test the DOA and pseudorange of arrival signals at the same time.Because of this,it can greatly improve the adaptability to different spoofing scenarios.This paper also gives the process to identify and eliminate spoofing signals in the received signals.In conclusion,the performance between the method based on the joint WSSE of DOA and pseudorange and the traditional method based alone on DOA or pseudorange is compared.The simulation results show that the proposed method is superior to the traditional way both in the adaptability to different spoofing scenarios and the detection performance.
