摘要: 航迹的模式识别可进一步为航迹预测、空域结构优化、空中交通态势监控提供支持。首先,对获取的自动相 关监视广播系统(ADS-B,automatic dependent surveillance-broadcast)数据进行筛选、处理,形成一系列的航 迹点集;其次,计算以航迹点组成的各航迹数据之间的相似度,按一定比例选取训练集和测试集;然后,以 训练集进行学习、训练,建立自组织神经网络(SONN,self-organizing neural network),获得竞争单元;最后, 输入测试集,通过所得神经网络对终端区航迹进行模式识别,分析其正确性。 仿真结果表明,该算法可较好 地识别终端区空域内航迹。

Abstract: The trajectory pattern recognition can further support track prediction, airspace structure optimization and air traffic situation monitoring. Firstly, a series of trajectory point sets are formed by screening and processing the initially obtained automatic dependent surveillance-broadcast (ADS-B) data. Secondly, the similarity degree between trajectory data composed of trajectory points is calculated. The training set and test set are selected according to a certain ratio; then, the training set is used for learning and training, and a self-organizing neural network (SONN) is established to obtain a competition unit. Finally, the test set is input and identified by the resulting neural network to analyze its correctness. Simulation results show that the algorithm can better identify the trajectory in the airspace of terminal area.

Key words: terminal airspace, trajectory classification, pattern recognition, self-organizing neural network (SONN)
