| description | The invention relates to a navigation deception signal detection method and device for a multi-beam array receiver. The method comprises the following steps: selecting two available satellite channels in a multi-beam array receiver as a first reference channel and a second reference channel; acquiring an intermediate frequency signal output by the radio frequency front end of the multi-beam array receiver; performing multi-beam anti-interference processing on the intermediate frequency signal according to the first reference channel and the second reference channel to obtain a first anti-interference output signal and a second anti-interference output signal; respectively capturing and tracking the first anti-interference output signal and the second anti-interference output signal to obtain carrier phase double-difference observed quantities among different available satellites, and obtaining detection statistics according to the carrier phase double-difference observed quantities and observed quantity lengt |
