| 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。 |

| Abstract: |
| In the field of air traffic control(ATC),the data rate of ADS-B receiver
in the Wide Area Surveillance System(WASS) is depressed because of the amount of
secon
dary planet from which ADS-B receive data reduces when the aircraft change its d
irection. And the data points lose seriously in the process of the aircraft land
ing. Tracking the aircraft is achieved with two models used to represent the sta
te of uniform motion of aircraft and uniformly accelerated motion, three-point s
peed direction forecast, and the model of the aircraft landing on the base of th
e characteristics of ADS-B data. Simulation based on the real data is done to va
lidate
the model. The results show that this method can effectively improve the data r
ate and the effect of tracking aircraft in the process of aircraft landing. |
