摘要
在空中交通管制(ATC)领域,广域监视系统中的ADS-B接收机在飞机飞行方向改变时,由于其收星的数量减少导致数据率变低,并且在飞机降落过程中丢点严重。结合ADS-B数据的特点,采用两个模型分别表示飞机的匀速运动和匀加速运动状态,利用三点速度方向预测修正对地速度,并引入飞机降落的先验模型,实现在广域监视中对飞机的有效跟踪。真实数据验证了该方法可有效提高数据率和改善飞机降落过程中的跟踪效果。
In the field of air traffic control（ATC）, the data rate of ADS - B receiver in the Wide Area Surveil- lance System（WASS） is depressed because of the amount of secondary planet from which ADS - B receive data reduces when the aircraft change its direction. And the data points lose seriously in the process of the aircraft landing. Tracking the aircraft is achieved with two models used to represent the state of uniform motion of air- craft and uniformly accelerated motion, three - point speed direction forecast, and the model of the aircraft land- ing on the base of the characteristics of ADS - B data. Simulation based on the real data is done to validate the model. The results show that this method can effectively improve the data rate and the effect of tracking aircraft in the process of aircraft landing.
