摘要/Abstract

摘要：

诱导式卫星欺骗干扰可诱导航空器逐渐偏离预定航迹，难以被发现，因此及时有效地检测干扰是飞行安全的保障。在现有紧组合导航体制基础上，设计了一种基于误差估值累加开环校正的紧组合导航结构，并证明了其性能与传统闭环校正紧组合导航性能等效。在此结构中，将紧组合导航系统与自适应序贯概率比检测方法结合，提出了一种基于误差估值累加开环校正的诱导式欺骗检测方法，融合紧组合导航信息与其他不受欺骗影响的导航信息，构建欺骗检测统计量进行诱导式欺骗检测。仿真结果表明，开环校正结构可避免随时间累加的惯性导航系统误差所导致的组合导航滤波器发散问题，同时欺骗检测方法可进一步提高算法对“最坏”情形下微小诱导式欺骗的检测效果。

Abstract:

Induced satellite spoofing interference can induce the aircraft to gradually deviate from the predetermined trajectory, and it is difficult to detect.So timely and effective detection of interference is the guarantee of flight safety.Based on the existing tightly integrated navigation system, an error valuation accumulation open-loop correction structure was designed.It was proved that the performance of the designed structure was equivalent to the performance of traditional tightly integrated navigation system with closed-loop correction.On the basis of designed structure, combining the tightly integrated navigation system with the adaptive sequential probability ratio test method, an induced spoofing detection method based on the error valuation accumulation open-loop correction was proposed.A spoofing detection statistic for induced spoofing detection was constructed by integrating the tightly integrated navigation information with other navigation information that was not affected by spoofing interference.Simulation results show that the designed open-loop correction structure can avoid the divergence problem of the integrated navigation filter caused by the inertial navigation system error accumulated over time.Moreover, the proposed spoofing detection method can improve the detection effect of the algorithm of the small induced spoofing under the “worst” case further.

Key words: induced spoofing interference, spoofing interference detection, tightly integrated navigation, open-loop correction, adaptive sequential probability ratio test
