In view of the lack of analysis of the relevant factors related to the anti-jamming performance of the satellite naviga-tion terminal from the perspective of signal processing,this paper focuses on the influence of the interference signal on the RF front-end,acquisition and tracking,and positioning and solution processes.RF front-end parameters associated with useful signal discrimination capability,azimuth stability,recovery time,acquisition sensitivity,reacquisition sensitivity,tracking sensitivity,tracking threshold acquisition and tracking process associated parameters,positioning accuracy retention capability,and data pro-cessing strategy positioning solution process associated parameters.Finally,the corresponding experiments are designed and ana-lyzed for each correlation parameter,and the specific influence of the proposed correlation parameters on the anti-jamming perfor-mance of the satellite navigation terminal is explained.
