数量剧增的无人机迫切需要与普通航空器共享非隔离空域资源,给本已十分繁忙的空中交通带来了安全隐患。由于在法规、通信、监视、可靠性和感知防撞方面,无人机尚未达到与有人机同样的安全水平,使无人机系统被有效整合进非隔离空域,成为各国航管组织亟待解决的重要问题。基于无人机防撞原理及非隔离空域类型,充分考虑空域威胁目标属性,制定无人机防撞需求标准,为无人机防撞系统的研制及相关空管标准规范的制定提供依据。 The increasing number of unmanned aerial vehicles is urgently needed to share non-isolated airspace resources with ordinary aircrafts, which poses a potential safety hazard to already busy air traffic. UAVs have not yet reached the same level of safety as manned aircraft in terms of regulations, communications, surveillance, reliability and perceptual collision avoidance, making UAVs effectively integrated into non-segregated airspace and becoming an urgent problem to be addressed by national air traffic control organizations. Based on the principles of unmanned aerial vehicles collision avoidance and the types of non-isolated airspace, this paper takes the airspace threat target attribute into consideration, and establishes the anti-collision requirement standard for unmanned aerial vehicles and provides basis for the development of unmanned aerial vehicle collision avoidance system and relevant air traffic control standards.
