提出了一种新的概率数据互联和粒子滤波相结合的新算法，并应用于杂波环境下的无源声纳系统中，该算法也可以很容易的应用于多目标情形。-There proposed a new method of data association called highest probability data association (HPDA) combined with

particle filtering and applied to passive sonar tracking in clutter.The proposed HPDA algorithm can

be easily extended to multi-target tracking problems.
