针对基本拓扑法的缺点,提出了用拓扑序列法进行航迹关联。新算法能避免空间划分不均匀、算法经验性太强、对密集航迹场景不适应等多种问题。新算法把航迹关联问题最终归结为假设检验,使算法的原理更严密。同时,通过多种辅助测试避免了不必要的航迹关联测试,使算法的计算效率非常高。针对工程应用的背景,对各种情况的算法修正也做了详细讨论。通过仿真,拓扑序列法比基本拓扑法具有更高的关联成功率和稳定的性能。
Focusing on the weaknesses of the basic topology track-to-track correlation algorithm,a topology sequence method is introduced.Many application dilemmas,such as uneven space division,an excessive number of heuristic parameters,poor adaption to dense track scenes,can be avoided by the new algorithm.Track-to-track correlation is viewed as a hypothesis test by the new algorithm which makes the theory more rigorous.Moreover,unnecessary topology tests are avoided by versatile auxiliary tests,which improves calculation efficiency greatly. To facilitate engineering application, procedure modifications for different conditions are discussed in detail. Simulation tests show that higher successful correlation ratio and more robust performance are provided by the topology sequence method.
