| 摘 要： | 近地告警系统的报警阈值的设定是研究告警系统技术过程中的一个重要问题。本文给出一种状态空间下的基于报警系统复杂性能指标的报警阈值的设计方法,该方法利用预先定义的包含不确定因素的轨迹模型,权衡报警和无报警之间的关系,以此来设定合适的报警阈值;最后,以近地告警系统模式1的阈值设置为例,在MATLAB环境中用Monte Carlo方法进行计算机仿真,验证了该报警系统阈值的设计方法。

| Abstract: | To design a reasonable warning threshold is a great significant problem in the research of the ground proximity warning system.A design method of warning threshold based on performance index of complicated warning system in the state space is proposed in this paper.This method can determine an applicable warning threshold by using the predetermined track model 1 with uncertainty factors and comparing the relationship between warning and no warning.In the end,taking the setting of GPWS model for example,through computer simulation with Monte Carlo method in the MATLAB environment,this design method is demonstrated with success. |
