摘　　要：随着空中交通流量的日益上升,空中交通警戒和防撞系统(TCAS)在保障飞行安全方面的作用越发重要。机动策略是TCAS的关键技术。介绍了TCAS机动策略的原理。具体论述了目标冲突过程中TCAS的交通咨询和决策咨询。建立数学模型,分析了空中交通警戒和防撞系统在不同空域情况下的机动策略。详细推导了TCAS的垂直规避算法和水平规避算法。最后对提出的算法进行了数字仿真和性能分析,验证了机动策略的可行性。Traffic Alert and Collision Avoidance System（TCAS） plays a more and more important role in flight safety with the constantly increasing air traffic flow.Maneuvering strategy is a key to TCAS.The principle of maneuvering strategy for TCAS was introduced.Traffic advisory and resolution advisory were presented concretely in the conflict process.Mathematical models were built up,and the TCAS strategies under different conditions of the airspace were analyzed in detail.The algorithms in vertical direction and horizontal direction were derived.The numerical simulations to the algorithms verified the reliability and feasibility of the strategies.
