| 摘要: |
| 在雷达环境杂波强、目标运动特性复杂、需要同时跟踪多批目标的情况下，目标跟踪过程中容易因关联错误造成跟踪错误。本文提出的多假设航迹跟踪方法在目标的机动特性不明时，建立航迹的多个假设航迹，对假设航迹进行隐形跟踪。该方法中航迹具有父、子、孙三类分支属性之一，其中父航迹为原始航迹，子航迹是在父航迹基础上建立的假设航迹，孙航迹是在子航迹基础上建立的假设航迹。通过父、子、孙三类分支航迹之间的继承和替代，可以同时跟踪丢点、密集杂波区、机动状态不明的多批目标，降低航迹关联错误的概率，实现对目标的稳定跟踪。 |

| Abstract: |
| To solve the problem of track error caused by association error when tracking multi- target in strong clutter environment and the movement characteristics is complex, a multiple hypothesis tracking method is proposed in this paper. When the maneuvering characteristic of the target is unknown, a number of hypothe- tical tracks are created for the original track and are tracked invisibly. In this method, the tracks have one of the three filiation attributes of father, son, or grandson, where the father track are the original track, the son tracks are the filiations of father tracks, and the grandson tracks are the filiations of son tracks. Though inheritance and substitution between the three filiation tracks, the targets can be tracked steadily whether they are in temporary disappearing, maneuvering, or in strong clutter. |
