摘　　要：随着全球导航卫星系统(GNSS)信号体制的不断更新,接收机应用环境越来越复杂,多径误差抑制技术也在不断发展进步。其中,基于改进基带的多径抑制算法由于成本和效果综合较优,受到了国内外研究人员的重视。论文首先阐述了GNSS多径抑制的基本原理,综述了传统的GNSS参量式和非参量式多径抑制算法的研究现状和实现方式,然后探讨分析了新体制信号中提高抗多径性能的方法,总结了当前GNSS多径抑制基带处理研究中的主要问题,最后展望了其未来的发展趋势。The enrichment of the Global Navigation Satellite System(GNSS) signal promotes the development of multipath mitigation technology. The multipath mitigation method based on baseband improvement can reduce the hardware cost and achieve excellent multipath mitigation performance, which are widely studied at home and abroad. Firstly, the basic principle of GNSS multipath mitigation is introduced. Secondly, the research status of multipath mitigation methods based on parametric and nonparametric methods is described. Thirdly, the multipath mitigation method of the new GNSS signal is demonstrated. Finally, the future trend of multipath mitigation methods is prospected.
