未来的欧洲全球导航卫星系统伽利略计划在L频段内的四个子频段(E5a、E5b、E6和E1)发射导航信号。也有其他应用在世界各地使用L频段，与全球导航卫星系统共享频谱或利用邻近频段。测量活动的报告表明，没有辅助的全球导航卫星系统接收器可能会在调频和电视广播发射机附近失锁。此外，在机场周围地区，甚高频无线电导航系统和甚高频通信系统可能对全球导航卫星系统接收器产生干扰。因此，必须更好地了解射频干扰对全球导航卫星系统接收器的影响，以便改进缓解办法。本文研究了窄带连续波对多载波伽利略导航信号捕获的影响，采用了明确的捕获技术(B&F、M&H、UAL)。据作者所知，这一主题以前没有在文献中研究过。
Galileo, the future European GNSS, is planning to transmit navigation signals in four sub-bands (E5a, E5b, E6 and E1) within the L band. There are also other applications which use the L band worldwide, sharing the spectrum with GNSS or utilizing neighboring bands. Reports of measurement campaigns have shown that unaided GNSS receivers could experience loss-of-lock near FM and TV broadcast transmitters Also, in the surrounding area of airports, VHF radionavigation systems and VHF communication systems can produce interference to GNSS receivers. Thus it is important to better understand the effects of RF interference to GNSS receivers, in order to improve mitigation solutions. In this paper we address the particular issue of the effect of narrowband CWI on the acquisition of MBOC Galileo navigation signal, using unambiguous acquisition techniques (B&F, M&H, UAL). This topic was not studied before in the literature, to the best of the authors' knowledge.
