基于空间多特征综合推理的航迹航路关联

针对航迹分类问题,研究了基于空间多特征的综合推理在航路判读中的应用。首先根据空管系统对航路以及飞机飞行的要求,对航迹航路相关问题进行建模。然后根据已知的传感器系统输出的目标特性(位置,航向)与已知的多个航路信息分别进行相关度计算,构造基本信任函数,通过对其融合,得到目标单特征识别结果。其中,通过合理地引入复合类,实现了对目标类别的广义信任分类。建立了多特征折扣融合算法,对多特征基本信任函数进行折扣后再融合,得到目标多特征识别结果。仿真结果以及空管实际数据测试表明:该算法不仅可以实现航迹分类,同时可以有效地降低分类的错误率。

Track-to-airline association based on multi-feature reasoning

Considering track classification problem, the application of complex reasoning in the multi-feature track decision is studied. Firstly, according to the requirements of air traffic control system for airway and flight, an association model of track-to-airline is developed. Secondly, similarities between target features(position, direction) and information of known tracks are computed, basic belief assignments are constructed and then the target single feature classification results are obtained by fusion. The introduction of meta-class brings out the generalized credit classification for targets class. A multi-feature discount method is developed, giving the discount on features' basic belief assignments before fusion to get the target multi-feature classification results. The simulations and the test on real data of air traffic control system show that the method not only make the track classification, but also decrease the fault rate of classification.
