| 摘 要： | 为了更好地解决密集杂波环境下的目标跟踪问题,弥补密集杂波环境下概率数据互联算法(PDA)误关联概率偏高的不足,在对现有的Viterbi数据互联算法进行深入分析的基础上,给出了一种计算两个量测之间互联概率的表达式,提出了一种基于两点量测的Viterbi数据互联算法(TM-VDA).仿真验证,TM-VDA能够很好地完成对目标的跟踪,特别是在密集杂波环境下误跟踪率较PDA大大降低.

| Abstract: | Aiming at solving the problem of target tracking in high-density clutter,remedying the deficiency of PDA that the correlation error ratio of is high in high-density clutter,based on a deep analysis to the existent Viterbi data association algorithm,an expression which can calculate the association probability between two measurements is given and an Viterbi data association algorithm based on two measurements(TM-VDA) is presented.The simulation results show that TM-VDA can track the target very well.Compare... |
