摘要
面对飞行流量持续快速增长、民航空域资源日益短缺的状况,对飞机间的潜在冲突进行有效探测,是避免飞机间危险接近或碰撞发生的关键。对飞机周围区域进行合理建模,给出了一种基于广播式自动相关监视(ADS-B)技术的确定型冲突探测算法,充分利用ADS-B报文提供的经度、纬度、速度和航向等信息及其报文高更新率等特点,预先排除无威胁飞机,然后分别从水平和垂直两个方向对飞机之间的冲突进行探测。运用Matlab进行功能仿真,结果表明该算法能有效排除无威胁的飞机,并且能够对有威胁的飞机及时给出告警。该算法对保证自由飞行条件下的飞行安全具有积极意义。
With continually rapid growth of flight flow and increasing shortage of civil aviation airspace, effective detection of latent aircraft conflicts becomes the key to avoid aircrafts＇ dangerous approach or collision occurrence. By es- tablishing reasonable model around aircraft zone, a deterministic conflict detection algorithm is presented based on ADS-B （automatic dependent surveillance-broadcast）, which first eliminates threatening aircraft, then de- tects aircraft conflict in horizontal and vertical directions respectively by making full use of the information such as longitude, latitude, velocity and heading of aircraft provided by ADS-B message and the ADS-B message characteristics including high-speed update rate. Matlab simulation is carried out about this detection algorithm, results show that this algorithm can remove no-threatening aircraft effectively, and timely warning can be given for threatening aircraft. This algorithm has positive significance to guarantee flight safety for free flight.
