摘要
对于T-RS多基地雷达系统,提出一种具有航迹质量管理的多目标跟踪算法,以解决多目标跟踪过程中航迹起始、航迹确认以及航迹删除等问题.采用累加的对数似然比(logarithm likelihood ratio,LLR)计算融合中心每个航迹的质量,并依据航迹判决规则把当前航迹分成四类,然后用相应方法处理这些航迹集合.仿真结果表明,该算法能对杂波中多个目标进行稳定可靠的跟踪.
An algorithm was proposed for tracking multi-target in clutter based on the T-R^s multi-static radar system, which was used as track quality control method to solve such problems as track initialization, track confirmation, track rejection , etc. The accumulation logarithm likelihood ratio was used to score every track＇s quality in fuse center, and the track test criterion was used to divide the current track into four groups. Finally a different method was provided to deal with every track＇s group. Simulation results show that the proposed algorithm can steadily track multiple targets.
