Abstract: In view of the increasingly complex space electromagnetic environment,users pay more attention to the receiver anti-jamming performance of satellite navigation．For testing receiver anti-jamming performance,a kind of method to construct test system was proposed．By using digital simulation technology and instrument driving technology based on script,and combining with signal simulation equipments,couplers,anechoic chamber to construct semi-physical simulation system,the test was realized．The effective carrier to noise ratio at the receiver was used as index of anti-jamming performance,and it was simulated by adjusting output power of the jamming signal transmitter．The simulation results show that the curve of bit error rate versus the effective carrier to noise ratio can be got by the system,which can provide reference for the Beidou receiver anti-jamming performance test．
