摘要
针对无人机极易对载人航空器造成冲突且不易被及时发现,利用ADS-B技术,借鉴航空器TCAS工作原理,为无人机研发一种冲突检测告警机载设备。该机载设备由冲突检测和告警算法2个功能模块组成,无人机通过ADS-B机载设备获取合作目标的空中交通情景意识,计算目标航空器与本机之间CPA矢量值,通过矢量决断算法,来判断二者是否存在潜在冲突并触发告警。仿真实验结果表明,该技术能对潜在的飞行冲突提前预警,有效降低冲突的发生概率。
For UAVs are prone to conflict with manned aircraft and are difficult to be timely detected,based on ADS B technology,and learned from the working principle of the aircraft TCAS,this paper developed a collision detection alarm airborne equipment for UAV.The equipment consists of two functional modules,which are conflict detection and alarm algorithms.The UAV acquires traffic situation awareness from the cooperative target by ADS B,and calculates CPA between the two aircrafts,then determines whether there is a potential conflict and triggers the alarm by vector sharing algorithm.Simulation results show that this proposed technique can effectively reduce the probability of collision in advance alarm of the potential flight collision.
