摘要：
Since the BeiDou navigation satellite system (BDS-3) was officially launched, and as the space electronmagnetic environment is becoming increasingly complex, and the received signal power is weak, the new B2 signal under strong interference poses new challenges and higher requirements for signal quality. The paper simulated the B2 signal and narrowband interference signal models, analyzed the effects of narrowband interference on power spectrum deviation, correlation loss and S-curve biases (SCB) under different parameters, such as intermediate frequency, bandwidth, and the jamming to signal ratio (JSR). And the real signal data collected by the 40-meter antenna system was used for verification. The results of the study show that the variation of interference signal parameters has a significant impact on the signal quality, and the signal quality deteriorates significantly when the interference environment is harsh, leading to large pseudorange measurement errors and affecting user positioning accuracy. The research results of this paper provide a valuable reference for interference monitoring assessment and signal quality assessment. © 2022, Editorial Office of Systems Engineering and Electronics.
