摘要
为了对使用临时航线的飞行轨迹进行准确识别,结合实际雷达轨迹数据与航线特征,提出一种基于单位距离面积(area per distance,APD)的临时航线飞行轨迹识别方法。首先根据航路范围构建待识别轨迹集合;然后分别计算飞行轨迹与临时航线标称航迹之间的APD值,并在此基础上进一步求得轨迹相似度;最后综合考虑准确率与查全率以确定最佳相似度阈值。以华北管制区实际数据为例,并与传统Hausdorff距离法识别效果进行对比,实验结果表明了本文所提方法的有效性。
In order to identify the flight trajectories of the conditional route,a method of recognizing the route trajectories was proposed based on the area per distance(APD)combining the actual radar trajectories data and the air route characteristics.Firstly,the set of trajectories to be recognized was constructed according to the route range;then the area per distance between the flight trajectories and the nominal track of the conditional route was calculated respectively,and the trajectory similarity was further obtained on this basis;finally,the best similarity threshold was determined by comprehensively considering the precision and recall.Taking the actual data of North China control area as an example,and comparing with the recognition effect of traditional Hausdorff distance method,the experimental results show the effectiveness of the proposed method.
