摘　　要：为了更准确地实现对导航干扰的性能评估和功能验证,提出用接收机干扰容限和干扰覆盖范围来衡量对卫星导航的干扰效果,并对带限白噪声、窄带和匹配谱三种不同干扰场景下6种现有体制的GPS信号进行了仿真分析和对比验证。仿真结果表明:三种干扰信号的干扰效果由强到弱依次为窄带、匹配谱和带限白噪声,信号抗干扰性能由强到弱依次为区域增强的M码、M码、P码、L5、L2C和C/A码。In order to more accurately achieve performance evaluation and functional verification of navigation interference, it is proposed to use receiver interference tolerance and interference coverage for measurement of the interference effect on satellite navigation. And in addition, the six GPS signals of existing systems in three different interference scenarios with band-limited white noise, narrowband and matching spectrum are simulated and compared. The simulation results indicate that the interference effects of the three kinds of interference signals, from strong to weak in order, are narrowband, matched spectrum and band-limited white noise, while the signal anti-interference performance, from strong to weak in order, being the area enhanced M code, M code, P code, L5, L2C and C / A code.
