摘要:

针对航路飞行阶段的航空器, 通过对比空间直角坐标系和大地坐标系的优劣, 采用大地坐标系表示航空器的位置; 基于大地坐标系, 将航空器的运动解耦成3个方向上的独立运动, 分别建立每个方向上的子模型; 使用交互式多模型(interacting multiple model, IMM)算法对航空器的航迹进行跟踪。仿真结果表明, 基于大地坐标系的IMM算法对于航空器有很好的轨迹追踪性能; 根据航空器末时状态及各个子模型的概率分布进行航空器的航迹短期外推, 基于大地坐标系的IMM算法的航迹外推性能优于基于空间直角坐标系的IMM算法的航迹外推性能。

Abstract:

Aiming at the aircraft in route flight phase, the geodetic coordinate system is used to represent the position of the aircraft after comparing the advantages and disadvantages of the space rectangular coordinate system and the geodetic coordinate system. Based on the geodetic coordinate system, the motion of the aircraft is decoupled into independent motion in three directions, and the sub models in each direction are established respectively. The interacting multiple model (IMM) algorithm is used to track the trajectory of the aircraft. The simulation results show that the IMM algorithm based on geodetic coordinate system has good tracking performance for aircraft. According to the aircraft terminal state and the probability distribution of each sub-model, the aircraft's trajectory is short-term extrapolated. The track extrapolation performance of the IMM algorithm based on the geodetic coordinate system is better than that of the IMM algorithm based on the space rectangular coordinate system.

Key words: air traffic management, trajectory tracking, short-term track extrapolation, interacting multiple model (IMM)
