Research on the influence of suppressive jamming signal on satellite navigation receiver
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.
