Abstract

To detect a spoofing signal transmitted by an attacker, a spoofing detection circuit forms a ranging circuit group by first selecting two or more ranging circuits each disposed at different locations. The spoofing detection circuit then requests and receives a set of measurements over a period of time from each ranging circuit in the ranging circuit group. Based on the received sets of measurements, the spoofing detection circuit estimates one or more locations for a target, a path of the target, or both. The spoofing detection circuit then determines whether the estimated locations or path of the target indicate spatial consistency or temporal consistency. Based on the estimated locations, estimated path, or both not indicating a spatial consistency, temporal consistency, or both, the spoofing detection circuit determines that a spoofing signal was received by the ranging circuit group.
