A novel distributed global satellite navigation synchronous spoofer, which is deployed as a pseudo-satellite constellation, sends several synchronous spoofing signals from different directions of arrival (DOAs). In this letter, we propose a synchronous spoofing monitoring method based on a spatial cross-correlation spectrum. The power and corresponding DOA measurements of those correlated sources are extracted by searching for the peak of the proposed cross-correlation spectrum. Experimental results demonstrate that the proposed method enables the simultaneous estimation of three essential features, such as DOAs, received power levels, and cross-correlations among different navigation signals, and effectively detects the synchronous spoofing signal at the moment when the monitoring correlation coefficients reach the maximum of 1.
