弹道目标航迹片段关联及优化

多弹道目标跟踪伴随着速度快、密集程度高以及测量误差大等因素,在跟踪过程中发生航迹中断是一个很普遍的现象.在未知导弹任何先验信息前提下如何将中断前后的航迹片段进行关联,提高航迹的连续性已成为亟待解决的难题.针对该问题提出了一种实时的离散最优关联算法,它利用速度信息对中断前后弹道外推航迹进行粗关联；将对数似然函数作为关联代...

Ballistic Target Track Segments Association and Optimization

Track breakage is a common issue in a multiple ballistic target tracking scenario with high speeds,high densities and large measurement errors.How to improve the track continuity by associating the break track segments without any prior information is therefore a focus of research efforts.This paper proposes a real-time discrete optimal association algorithm which uses the velocity information to realize coarse association for extrapolation between the break track segments and improves the association proba...
