摘　　要：全球卫星导航系统(GNSS)与多传感器组成的融合定位系统由于其精确性和鲁棒性,已经在自动驾驶和无人探测等领域得到广泛应用。然而,GNSS容易受到欺骗干扰影响,导致融合定位系统输出错误信息,进而引发严重后果。鉴于传感器能够提供不受GNSS欺骗干扰的载体状态信息,融合定位系统能够通过GNSS和传感器信息的相互校验实现欺骗检测。本文对此类GNSS欺骗检测技术进行了综述,首先概述了GNSS/多传感器融合定位的传感器组成和信息融合算法;其次将现有GNSS/多传感器定位中的欺骗检测技术分为独立信息一致性监测和信息融合异常检测2类,并总结分析了不同算法的基本原理、实现方法和性能效果;最后对GNSS/多传感器融合定位中欺骗检测技术的未来发展趋势进行了展望。The fusion positioning system composed of global navigation satellite system(GNSS)and multiple sensors has been widely used in fields such as autonomous driving and unmanned detection due to its accuracy and robustness.However,GNSS is vulnerable to spoofing,leading to incorrect positioning information output and further resulting in serious consequences.Given that sensors can provide carrier state information which is independent from GNSS spoofing,fusion positioning systems can achieve spoofing detection through information verification of GNSS and multi-sensor.This paper provided an overview of such GNSS spoofing detection technologies.Firstly,the sensor composition and information fusion algorithms for GNSS/multisensor fusion positioning were outlined.Secondly,the existing spoofing detection technologies for GNSS/multi-sensor fusion positioning were divided into two categories:independent information consistency monitoring and information fusion abnormality detection.The basic principles,implementation methods,and performance effects of different methods were summarized and analyzed.Finally,the future development trends of spoofing detection technologies were discussed.
