超宽带信号对北斗信号干扰分析
|
摘要
超宽带(UWB)信号频谱可覆盖北斗(BDS)导航信号频率范围,对北斗接收机的正常工作造成干扰威胁。针对这一问题,通过理论分析、计算机仿真并结合真实北斗B1信号,研究了在跳时-脉位调制(TH-PPM)方式下的UWB信号对北斗软件接收机的干扰情况,并给出了减轻干扰的途径。
The ultra-wideband( UWB) signal spectrum can cover the frequency range of the Beidou navigation satellite system( BDS),which poses a threat to the normal operation of the Beidou receiver. In this paper,the interference of UWB signal to Beidou software receiver under TH-PPM modulation mode is studied by theoretical analysis,computer simulation and real Beidou B1 signal compared,and the approach of interference reduction is provided.
