在深入分析Viterbi算法的基础上,对现存的基于Viterbi的数据关联算法作出了一定的修正,提出了一种改进的基于Viterbi的单目标数据互联算法(IVDA),有效地完成了对单目标的跟踪,并解决了PDA算法在目标检测概率较低时误跟踪率偏高和杂波密度参数在实际中难以获取的问题,最后通过仿真验证了结论的正确性。
Based on a deep analysis to the Viterbi algorithm,an modification on the existent data association algorithm based on Viterbi is presented,and a improved single target data association algorithm(IVDA) is proposed.The algorithm could effectively track the single target,and resolve the problem of PDA that the error tracking probability is high when the target detection probability is low and the clutter density parameters are difficult to get in fact.In the end the simulation results show that the conclusion is correct.
