基于航迹似然性的一体化目标跟踪算法研究

摘要

针对目前大多数目标跟踪算法解决的只是目标跟踪过程（航迹起始、数据关联、航迹维持和航迹终止）中的部分问题，探讨了如何将目标跟踪的整个过程在一个算法中完整体现的可能性。通过研究，发现了航迹似然性这一有效参量，在此基础上提出了基于航迹似然性的一体化目标跟踪算法。在目标跟踪过程中，该算法通过航迹假设、利用航迹似然性参数能够及时发现新目标、较准确的关联数据、更新航迹、终止消失目标航迹。仿真结果表明，该算法能够实时地实现对杂波环境下雷达目标的一体化跟踪。%Aiming at the fact that most target tracking algorithms could resolve one or some of the problems of entire target tracking which includes track initiating ,data association ,track maintaining and track terminating ,the paper discusses the probability of realizing the whole process of tracking in one algorithm .Through research ,a parameter is found ,which is named track‐probability .On the basis of track‐probability ,the integrated target tracking algorithm based on track‐hypothe‐ses is proposed .While tracking targets ,the proposed algorithm could detect new targets timely ,associate data and update exactly and terminate tracks of disappeared targets .The simulation indicates that the algorithm could realize integrative track the radar targets in clutter in time .
