基于几何法的航迹关联算法研究

Research on Track Correlation Algorithm Based on Geometric Method

为更好地适应工程应用上的需求,提出一种基于几何法的航迹关联算法,把每一条航迹线看作具有一定宽度的航迹带,通过计算另一航迹在航迹带中的长度占自身总长度的比例来判断两条航迹是否关联,针对算法效率问题给出了航迹简化的思路,并且编程实现了上述所有算法。用仿真试验验证了算法的有效性和正确性。

To better meet the requirement of engineering application,a track association algorithm based on geometric method is proposed,each track line is considered as a track belt with a certain width,calculating the ratio of the length in the track belt to its total length of the other track tojudge whether the two tracks are correlated.A thought of track simplification is proposed according to the efficiency of the algorithm,and all the above algorithms are realized by programming.Finally,the effectiveness and correctness of the algorithm are verified by simulation experiments.
