摘要
提出了一种新的多目标跟踪快速数据关联算法 .重点分析了关联门相交区域中的公共回波对航迹更新的影响 ,并综合考虑了关联门内其余候选回波对航迹更新的作用 ,以很小的计算代价完成了后验概率的计算 .仿真表明 ,新算法以与PDAF算法接近的计算量 ,达到了接近于JPDAF算法的目标跟踪成功率 .
A new fast algorithm is presented to solve the data association in multitarget tracking in cluttered environment. The new algorithm exactly analyzes the impact of the public measurement in the intersection of validation gates for fast computation of the a posteriori probability .The simulation shows that the successful ratio of the new algorithm approximates JPDAF with slightly increased CPU times in comparison with PDAF in multitarget tracking.
