“…In addition, spoofing equipment can also forward actual signals, increase signal delay, and achieve the intended deception. Ultimately, these spoofing interference signals can cause errors in the receiver's positioning results [31]. Regarding the characteristics of DOA estimation for satellite navigation interference sources, firstly, due to the similarity between spoofing signals and actual signals and the low SNR, DOA estimation algorithms need to work properly under low SNR conditions to measure the direction of the spoofing interference signal.…”

Direction of arrival (DOA) estimation is an effective method for detecting various active interference signals during the satellite navigation process. It can be utilized for both interference detection and anti-interference applications. This paper proposes a DOA estimation algorithm for satellite interference sources based on frequency domain covariance matrix reconstruction (FDCMR) to address various types of active interference that may occur in the satellite navigation positioning process. This algorithm can estimate the DOA of coherent signals from multiple frequency points under low signal-to-noise ratio (SNR) conditions. The signals received from the array are transformed from the time domain to the frequency domain using a fast Fourier transform (FFT). The data corresponding to the frequency point of the target signal is extracted from the signal in the frequency domain. The frequency domain covariance matrix of the received array signals is reconstructed by utilizing its covariance matrix property. The spatial spectrum search method is used for the final DOA estimation. Simulation experiments have shown that the proposed algorithm performs well in the DOA estimation under low SNR conditions and also resolves coherency. Moreover, the algorithm’s effectiveness is verified through comparison with three other algorithms. Finally, the algorithm’s applicability is validated through simulations of various interference scenarios.

Global Navigation Satellite System (GNSS) spoofing interference poses a great threat to the security of end users. Based on the same propagation path characteristics of the spoofing signals transmitted by a single antenna spoofing device, this paper proposes a method against single antenna spoofing jamming utilizing the Fréchet distance of Doppler frequency difference. When the receiver moves, the Doppler data in a window are fitted via the leastsquares method, and the Fréchet distance between the two satellite signals is calculated to obtain the similarity evaluation value between them. The detection of spoofing signal is carried out based on the evaluation value. We use real data to verify the detection performance of the method, and the experimental results show that the method can effectively distinguish the spoofing signal from the authentic signal. In addition, the method has low computational complexity and requires less additional information, which makes it possible to apply it in the anti-spoofing module of a GNSS receiver.
