DECEPTION SIGNAL DETECTION SYSTEM AND DECEPTION SIGNAL DETECTION METHOD

摘要

To be able to detect a deception signal disguised as a navigation signal such as a GSP signal.SOLUTION: A deception signal detection system according to the embodiment includes: a first antenna for receiving a plurality of four or more navigation signals, each indicating a transmission position and a transmission time of the signal; a second antenna for receiving the plurality of navigation signals; and a signal processing system that determines whether a plurality of four or more radio signals that is the plurality of radio signals received by the first antenna and the second antenna respectively indicating the transmission position and the transmission time of the signal, are the plurality of navigation signals or the deception signals based on the plurality of radio signals.SELECTED DRAWING: Figure 1
