Abstract

Presently, the approaches for detecting and suppressing various forms of spoofing interference are undergoing rapid development. The spoofing interference detection approach based on spatial information is capable of effectively detecting spoofing assaults originating from stationary locations. Nevertheless, this approach has notable limitations and downsides, since it necessitates the use of an antenna array for signal reception, which may be expensive and operationally intricate. In order to tackle these problems, we suggest a spoofing interference detection technique that relies on a rotating single antenna. This technique necessitates the use of a solitary spinning antenna to identify counterfeit signals that arrive from a direction that does not match the actual arrival direction. The distinguishing factor for detecting differentiation is the disparity between the direction of arrival of the spoofing signal and the actual signal. Spoofing interference detection is achieved by comparing the estimated value of the signal's arrival azimuth with the theoretical value acquired from ephemeris information. This is done to ensure consistency in the paired signal arrival azimuth discrepancies between the estimated and theoretical values. Moreover, the generalized likelihood ratio test is employed to identify numerous arrival directions of spoofing signals. This paper substantiates and assesses the suggested approach by means of software simulation analysis and experimental verification. The findings demonstrate that this strategy may successfully achieve the desired detection outcome.
