摘　　要：针对缺少不同样式、带宽和频偏参数压制式干扰信号对卫星导航接收机作用效果的全面分析,文中基于卫星导航接收机跟踪门限和码跟踪误差,采用仿真方法分析了不同干扰参数信号对跟踪过程的影响,分析出BPSK和QPSK调制信号的干扰样式效果较好,且最佳干扰带宽、中心频率并不一定等于导航信号带宽和中心频率。文中通过搭建室外、室内实验环境,进一步验证了不同干扰信号参数对卫星导航接收机的影响,其结果与仿真结论基本一致。Based on the lack of comprehensive analysis of the effect of the satellite navigation receiver with different styles,oppressive jamming signal bandwidth and deviation parameters comprehensive analysis of the effect of the satellite navigation receiver,based on the satellite navigation receiver tracking threshold and code tracking error,the simulation method is used to analyze the influence of signals from different jam⁃ming parameters on the tracking process.As a result,the analysis of BPSK and QPSK modulation signal jamming pattern effect is better,and the optimal jamming bandwidth and center frequency are not necessari⁃ly equal to the bandwidth and center frequency of navigation signal.By building outdoor and indoor experi⁃mental environments,this paper further verifies the influence of different jamming signal parameters on the satellite navigation receiver,and the results are consistent with the simulation conclusions.
