针对空间电磁环境的日益复杂化，卫星导航接收端抗干扰性能成为北斗用户密切关注的问题，为了测试动态导航接收端的抗干扰性能，提出一种室内无线抗干扰性能测试系统构建方法。采用基于灰色关联分析的场景映射方法、基于脚本的仪表驱动技术，结合信源模拟设备、微波开关、微波暗室等构建半实物仿真平台。不断调节干扰信号发射端输出功率，改变接收端有效载噪(C/N0)，据此获得导航接收端失锁时的输入信干比(J/S)。仿真结果表明：通过干信比与有效载噪比的关系曲线，实现对接收端的抗干扰性能测试，为卫星导航接收端抗干扰性能测试提供测试平台。

The anti-jamming performance of the Beidou navigation satellite receiver attracted the users'extensive attention due to the increasingly complex electromagnetic environment. A indoor wireless anti-jamming performance test system for the Beidou dynamic receiver was proposed. Semi-physical simulation system is constructed in anechoic chamber by the combination of scene mapping based on grey relational analysis (GRA), instrumentation script-based drive technology and corresponding simulators, microwave switches. By adjusting the output power of the interference, and the receiver effective carrier-to-noise ratio (C/N0), where is used to represent the anti-jamming performance, then the jam-to-signal ratio (J/S) can be obtained when the receiver is loss of lock. The simulation results show that the anti-jamming performance test of the receiver can be reflected by J/S versus C/N0 curve, and this method provides a test platform for the Beidou receiver anti-jamming performance test.
