| 摘 要： | 基于测量域提出了新的导航系统完好性度量算法。充分考虑所需导航性能参数和不确定的噪声的因素，运用概率优化方法进行故障监测。选择适当的性能参数，与漏检率具有一一映射关系，估算故障概率，并对此进行了讨论。在该算法中，利用残差灵敏度矩阵的各个特点提高识别有误差观测数据的效率。该算法可用于完好性监测的性能要求规定，计算高效。非精密进近的仿真结果证明了该算法的有效性。 |

| Abstract: | A new integrity metric for navigation systems is proposed based on the measurement domain. Probabilistic optimization design offers tools for fault detection by considering the required navigation performance (RNP) parameter and the uncertainty noise. The choice of the proper performance parameter provided the singlevalued mapping with the missed detection probability estimates the probability of failure. The desirable characteristics of the residual sensitivity matrix are exploited to increase the efficiency for identifying erroneous observations. The algorithm can be used to support the performance specification and the efficient calculation of the integrity monitoring process. The simulation for non-precision approach (NPA) validates both the viability and the effectiveness of the proposed algorithm. |
