灰色航迹关联算法的分析与改进

Analysis and Improvement of the Grey Track-track Association Algorithm

研究并改进了灰色航迹关联算法。通过引入雷达自动检测理论中的双门限信号检测法,在原灰色航迹关联算法中设置双门限,提出了基于双门限的灰色航迹关联算法。经过仿真,改进后的新算法,将航迹平均关联正确率在原灰色航迹关联算法的基础上提高了1.42!。最后,对所有涉及的航迹关联算法进行了综合对比,分析了改进后的双门限灰色航迹关联算法的优势及适用环境。

The grey track-track association algorithm is studied and improved. Through being introduced double-threshold signal detec- ting approach from the theory of radar automatic detecting, the grey track-track association algorithm is put forward, which based on double threshold by intercalating two thresholds in the former grey track-track association algorithm. As a result of the simulation, the new improved algorithm, compared with the former grey track-track association algorithm, increases 1.42% percent on their average cor- rect rate of track association. Finally, the paper synthetically contrasts all the referred track-track association algorithms, and analyzes the advantages and application conditions of the new improved grey track-track association algorithm based on double threshold.
