摘　　要：TCAS是一系列独立于地面空中交通管制(ATC)系统运作的机载设备,为各机型的民航客机提供避碰保护。所有的TCAS系统都提供一定程度的碰撞威胁警告和交通显示。TCASⅡ系统由TCAS计算机、Mode S应答机、Mode S/TCAS控制面板、天线等主要部件组成。TCASⅡ系统与飞行员的接口由2个显示提供交通显示和避让建议显示。TCAS独立于任何地面输入,对附近的飞机进行监视,提供这些飞机的位置和高度信息,以便碰撞回避算法可以执行其功能。碰撞回避的核心是碰撞回避系统逻辑或CAS逻辑。本文对CAS逻辑的运作,需要理解灵敏度级别、τ(TAU)和受保护体积等基本CAS概念进行了介绍和分析。TCAS is a family of airborne devices that function independently of the ground-based air traffic control(ATC)system,and provides collision avoidance protection for a broad spectrum of aircraft types.All TCAS systems provide some degree of collision threat alerting and a traffic display.A TCAS Ⅱ installation consists of the following major components:TCAS computer unit,Mode S transponder,Mode S/TCAS control panel,antennas.The TCAS interface with pilot is provided by two displays:the traffic display and the resolution advisories display.Independent of any ground inputs,TCAS performs surveillance of nearby aircraft to provide position and altitude information of these aircraft so that the collision avoidance algorithms can perform their functions.The heart of collision avoidance is the collision avoidance system logic,or the CAS logic.In this paper,the operation of the CAS logic and the basic CAS concepts such as sensitivity level,TAU and protected volume are introduced and analyzed.
