摘要:

雷达对多目标进行跟踪时,传统跟踪算法都是基于单帧递推思想进行实现的,只考虑多目标回波单帧信息,容易存在较大误差。为综合考虑目标的多帧信息,提出一种基于航迹随机集的多目标自适应航迹整体估计算法。首先基于航迹随机集生成观测区域内的多个航迹候选量测序列,而后对这些量测序列进行多项式时间序列分析并进行航迹整体估计,直接生成多目标运动轨迹。航迹随机集通过航迹假设思想能够同时考虑目标的多帧运动信息,大大降低杂波环境对多目标跟踪效果造成的影响;而航迹整体估计方法直接估计目标的整体航运动特性,其模型可随观测数据的到来实时调整变化,可以获得连续时间区间上任意时刻的目标状态。仿真结果表明,基于航迹随机集的多目标自适应航迹整体估计算法能够在杂波环境下对多目标进行有效跟踪,且相较于传统算法,该方法生成的整体航迹更为平滑且有着更好的多目标跟踪效果。

Abstract:

When tracking multiple targets with radar, traditional tracking algorithms are typically implemented based on single-frame recursive processing. As these methods only consider single-frame information from multi-target echoes, they tend to accumulate significant errors. To comprehensively utilize multi-frame target information, this paper proposes a multi-objective adaptive trajectory-oriented estimation algorithm based on trajectory random finite sets. The method first generates multiple candidate measurement sequences within the observation area using trajectory random sets, then performs polynomial time series analysis on these measurement sequences to achieve holistic trajectory estimation, thereby directly generating complete motion trajectories for multiple targets. The trajectory random set approach incorporates multi-frame motion information through trajectory hypothesis modeling, significantly reducing the impact of clutter environments on multi-target tracking performance. Meanwhile, the holistic trajectory estimation method directly estimates the complete motion characteristics of targets. Its adaptive model can dynamically adjust with incoming observation data, enabling continuous-time state estimation at arbitrary moments within the observation interval. Simulation results demonstrate that the proposed algorithm achieves effective multi-target tracking in cluttered environments. Compared with conventional algorithms, this approach generates smoother complete trajectories and exhibits superior multi-target tracking performance.

Key words: multiple target tracking, trajectory-oriented estimation, trajectory random finite set, polynomial time series analysis
