摘要

摘要: 完好性信息的实时检测对于保证陆基增强系统（GBAS）基准站无故障运行至关重要，其中多基准接收机一致性检测（MRCC）的B值是GBAS地面完好性检测的重要参数之一。但传统的MRCC只能检测出故障基准站进而排除其所播发的改正信息，无法分析出基站信号的异常类型和程度。本文讨论了GBAS系统的故障模型，提出了一种基于希尔伯特—黄变换（HHT）的完好性信息异常检测方法。利用经验模态分解（EMD）故障信号，通过对分解后信号分量的分析实现地面基准站故障情况的检测，该方法的斜率检测误差范围在10%以内，为GBAS地面基准站在完好性检测方面提供更加及时、准确的数据支持。

Abstract: Real-time detection of integrity information is critical to ensure trouble-free operation of the Ground Based Augmentation System (GBAS) reference station. Among them, the multiple references consistency check (MRCC) B-value is one of the important parameters of GBAS ground integrity detection, but MRCC can not analyze the type and extent of signal anomaly. In this paper, the fault models of the GBAS system are discussed, and an integrity information anomaly detection method based on Hilbert-Huang transform (HHT) is proposed. This method uses empirical mode decomposition (EMD) fault signals to detect GBAS reference stations faults by analyzing the decomposed signal components. The detection error range of this method is within 10%, which provides more timely and accurate data support for GBAS ground reference station integrity detection.
