摘要：
To suppress the repeater spoofing interferences effectively, a method of acquiring long code based on the match filter arithmetic is proposed by using delay-waiting strategy. The technical implementing process was also presented. Then the effectiveness of the scheme was deeply analyzed in theory when the repeater jamming exists in the environment. The limitation of this method was also investigated in theory in the scene of strong repeater jamming. Simulation on this scheme was carried out with the existence of repeater jamming. The simulation results validate the theory analysis. This positive result provides a theoretical and practical reference for the design of military anti-jamming satellite navigation receivers.
