摘　　要：基于多种导航信息综合处理、告警计算的近地告警系统,对于避免可控撞地事故、提升飞机安全具有重要意义。本文首先介绍了近地告警系统的工作原理,研究了基于SOC曲线的告警包线设计技术,并以过大近地速率告警模式为例进行了告警包线的仿真。最后,利用实际飞行数据分析验证了告警包线合理性以及导航信息可靠性对系统性能的影响。Based on the comprehensive processing and the alarm calculation of multiple navigation information,Ground Proximity Warning System is of great significance for avoiding controlled flight into terrain accidents and improving aircraft safety.First,the paper introduces the working principle of Ground Proximity Warning System,and studies the design technology of the alert envelope based on the SOC curve.Second,as an example,the warning mode of the high near ground rate is taking to simulate the alerting envelope.Finally,by using the actual fighting data,the rationality of alerting envelope and the reliability of navigation information are analyzed to affect the performance of the system.
