ABSTRACT:
Methods and systems for detecting GNSS signals originating from an inauthentic source. A synthetic array using a receiver antenna which is randomly spatially translated may be used to gather alleged GNSS signals. The signals are then processed to determine the spatial correlation between them. A high spatial correlation between the signals indicates a probable inauthentic source for the GNSS signals.
