摘　　要：传统的航迹管理方法在处理航迹起始、跟踪和终结时需用到不同算法,这无疑增加了航迹管理的复杂性。文中借助综合概率数据互联(IPDA)算法中考虑目标存在概率的思想,结合打分方法提出了一种新的航迹质量管理算法。该算法利用目标存在概率的信息不仅能对目标航迹进行更好地跟踪,同时可以判定航迹的起始和终结。仿真结果表明该算法跟踪性能优于PDA算法,并能够通过调节初始存在概率和质量的满分值来达到合适的起始和终结反应时间。仿真结果验证了算法的正确性和有效性。In traditional approaches of track quality management, if target tracks need to be initiate, track or terminate, different algorithms will be used. In this case, it will increase the complexity of track management. A new track quality management by using scoring method and the probability of track existence is presented in this paper, which based on integrated probabilistic data association （IPDA）. The results of the simulation experiment show that this algorithm has better tracking performance than PDA; meanwhile it can satisfy required initial reaction time and terminal reaction time by changing the existence probability and the full score. The simulation results demonstrate that this algorithm is correct and effective.
