摘要:

为解决通用航空尧无人机等小型飞机的空中冲突探测与防撞问题,设计了基于ADS-B 的机载防撞告警系统。通过被动式接收ADS-B 广播报文信息实现空空监视,然后基于空空监视态势信息,提出一种区别于传统TCAS 防撞算法的冲突探测和防止虚警方法,实现碰撞威胁探测和告警。利用实际采集的ADS-B 数据进行不同碰撞场景仿真验证,仿真结果表明:该系统能有效感知飞机周边交通情况,发出告警和取消告警时间均符合规则,可为小型飞机防撞提供工程应用解决方案,其成本尧重量和功耗远小于传统TCAS 设备。

Abstract: In order to solve the problem of conflict detection and collision prevention of small aircrafts, such as general aviation and UAV and so on, an airborne collision and alarm system based on ADS-B is designed. Air-to-air surveillance is realized through passive reception of ADS-B broadcast message information. Then based on airto-air surveillance situation information, a conflict detection algorithm which is different from the traditional TCAS and a method for preventing false alarm are proposed to realize collision threat detection and alarm. The conflict detection algorithm is verified by simulation with the actual ADS-B data and setting different conflict scenarios, proving that the current system provides engineering application solutions for small aircraft collision avoidance; meanwhile, the cost, weight and power consumption of the current system are much lower than
traditional TCAS equipments.

Key words: TCAS, ADS-B, traffic collision avoidance and alarm, air-to-air surveillance
