机载间隔保持系统建模及仿真

Model and Simulation of Airborne Separation Assurance System

空中间隔保持是让飞机获得所处空域的交通态势,在尚未构成威胁而告警以前,预先自主保持间隔,维持对空中交通态势的自我警觉。其作用和责任是不能由基于空域组织的战略级冲突管理、近距离的机载交通防撞系统所替代。本文提出利用ADS-B、ACAS信息源的空中间隔保持系统,研究了系统模型并进行了仿真测试,验证了系统具有的自主冲突探测与规避能力,系统融合ADS-B和ACAS信息,间隔保持到近距离的防撞系统可平稳过渡,过渡区实现双重覆盖。

Airborne separation assurance is mainly used to make the carrier aircraft in the air obtain the traffic situation, pre-keep safe separation from other aircraft before dangerous separation, so as to maintain self alertness for the air traffic situation. Its usage and responsibility can’t be replaced by strategic conflict management which are based on airspace organization and short range ACAS. This article proposes the airborne separation assurance system which uses the information source of ACAS and ADS-B, studies the system model and carries out simulation test to verify the capability of self conflict detecting and avoidance, the system fuses the information of ACAS and ADS-B to realize transition from range of airborne separation assurance to range of ACAS, and the transitional zone could be dual covered.
