摘要
提出了一种观测量组合算法对完好性风险进行了监测;并针对多接收机单统计量的线性组合进行了讨论;最后利用实际数据对该统计方法进行验证。研究结果表明:在发生失效的情况下,观测量组合算法能够更快地监测故障的发生,提高了对故障的检测速度,同时可检测出小偏差故障,降低系统的漏检率。
In this paper, a measurements combination algorithms method used to monitor the integrity risk is proposed. The linear combination for the single statistic value and multi-receivers is discussed. A simulation test with the data collected from the Fang Shan observation station in Beijing is performed. The simulation results show that this algorithm can detect the faults more quickly and improve the detection speed. It also can detect some little deviation; decrease the miss-detection rates of the system.
