针对低精度雷达的数据关联和目标机动跟踪问题,在此介绍了一种改进的α-β滤波算法,该方法通过引入隶属度函数,很好地解决了该体制雷达下的数据关联和目标机动判断问题,提升了数据关联及目标机动判断的准确性.工程实践证明,该方法应用于航迹起始和机动目标跟踪中,大大提高了跟踪的性能,具有很好的实用性.%A improved algorithm of α-β flitering is introduced in this paper to solve the problems of data association and maneuvering target tracking of low accurate radar. The ploblems of target maneuvering judgement and data association were successfully solved by introduing the membership functioninto the method. The accuracy of data association and maneuvering target tracking is greatly improved. The engineering practice proves that the method is feasible and effective in track initiation and maneuvering target tracking, and improves the tracking performance greatly.
