Abstract
A system for identifying spoofed navigation signals includes a multi-element antenna configured to receive a plurality of navigation signals. The system also includes at least one processor configured to obtain a gain vector for each of the navigation signals and analyze the gain vectors for the navigation signals to determine whether one or more of the navigation signals are spoofed. To analyze the gain vectors for the navigation signals, the at least one processor may be configured to (i) determine whether at least a specified number of the navigation signals have substantially the same gain vectors and (ii) in response to determining that at least the specified number of the navigation signals have substantially the same gain vectors, determine that the navigation signals having substantially the same gain vectors are spoofed.
