An Optimal Plot-to-Track Association Method Based on JVC Algorithm for Maritime Target with Compact HFSWR

  • 摘要: 紧凑型地波雷达由于接收天线阵列孔径减小导致对海上目标的定位精度低,在多目标跟踪算法中采用序贯式的点迹-航迹关联方式易发生误关联导致航迹断裂、误跟踪等问题。对此,该文将多目标点迹-航迹关联转化为最优分配问题,提出一种基于JVC算法的多目标点迹-航迹最优关联方法。对于关联波门重叠区域内存在公共候选点迹的多条航迹,首先以雷达获取的目标多普勒速度、距离与方位角作为目标特征参数,利用最小代价函数确定公共候选点迹与所有航迹之间的相似度,得到关联代价矩阵;然后以总关联代价最小化作为优化准则,采用JVC算法求解得到最优的点迹-航迹关联结果。利用仿真与实测目标数据开展了点迹-航迹关联实验,并与序贯最近邻关联方法的关联结果进行了对比。实验结果表明:采用该文所提方法跟踪得到的航迹时长明显优于序贯最近邻关联方法的结果,解决了序贯式关联因关联错误导致的航迹断裂、误跟踪等问题,提高了航迹跟踪的连续性。
