摘要
幅相误差对卫星导航系统抗干扰后输出信号的信干噪比及相对捕获峰值有较大影响。通过理论和大量仿真实验分析了幅相误差对抗干扰后输出信干噪比及相对捕获峰值的影响,并通过仿真实验分别对比分析了相位和幅度校正对抗干扰后输出信干噪比及相对捕获峰值影响,得到以下结论:相位校正对抗干扰性能的提升效果明显,而幅度校正对抗干扰性能的提升效果有限。
The amplitude and phase error have a great impact on the SINR and relative capture peak of the anti-jammed signal of the satellite navigation systems. Theoretical analysis and a large number of simulation are given to analyze the impact of amplitude and phase errors on the SINR and relative capture peak of the anti-jammed signal, and a large number of simulation experiments are also given to respectively compare and analyze the impact of the phase and amplitude correction on the output SINR and relative capture peak in the anti-jamming satellite navigation systems, then the following conclusions can be drew：. Phase correction has a significant enhancement on the anti-jamming performance, while the enhancement of amplitude correction is limited.
