摘　　要：无人机与有人机在多机种和不同合作程度下共享空域飞行是未来的发展趋势,防撞问题成为制约无人机飞出隔离空域的关键挑战。结合现有飞机防撞体系,从无人机防撞特殊性出发分析无人机自主防撞需求,提出无人机自主防撞系统的框架,归纳分析两大主要关键技术——感知探测技术和防撞算法,以及二者的不同应用范围和主要问题,在此基础上提出无人机自主防撞管理体系架构,总结探讨无人机自主防撞关键技术的发展趋势。Sharing airspace with manned aircrafts in different degree of cooperation is the future trend of un- manned aerial vehicle（UAV） operations, and collision avoidance issues become key challenges hindering UAV from flying heyond segregated airspace. Reqliirements of autonomous collision avoidance for UAV are analyzed from tile perspective of the particularity of the UAV collision avoidance combined with current layered aircraft collisiou avoidance strategies, and framework of UAV autonomous collision avoidance system is proposed, Two key techniques and their application scope and main issues of UAV autonomous collision avoidance are analyzed and discussed inductively, i.e. sensing technologies and collision avoidance algorithms, and on this basis man- Finally, development trends of UAV autonomous
