摘　　要：针对BAT(Brainpower Antitank)智能子弹药声探测系统不能定距问题,提出一种在仅有方向角信息条件下对地面机动声目标跟踪算法。首先分析了BAT声探测系统做三维运动时的定向算法;然后结合弹体运动特点,给出一种仅利用目标方向信息对地面机动目标跟踪算法,分别推导了目标静止、匀速、匀加速以及更高阶次运动时的角跟踪公式,并指出了定向误差存在的前提下其成立的充分条件;最后,给出了一个该算法的精确度函数,可以量化评估算法的精度,优化跟踪轨迹。理论分析表明BAT不需要在水平方向上做出比机动目标更高阶次的运动即可实现对目标的角跟踪。Associated that BAT （Brainpower Antitank） submunition acoustic detection system cannot fix distance, the bearing-only tracking algorithm of maneuvering acoustic target on ground with BAT is presented in this paper. Firstly the direction algorithm of BAT acoustic detection system is analyzed. Secondly the bearing-only tracking algorithm of maneuvering acoustic target on ground is deduced combined with the characteristics of the motion of projectile body. The corresponding formats of bearing- only tracking are separately deduced when acoustic target are stationary, uniform speed running, in uniform acceleration motion and in other higher phase motions. The sufficient conditions of above formats are given in the presence of direction error. Finally the accuracy function of this algorithm is given which can evaluate the accuracy of the algorithm and optimize the tracking path. The theoretical analysis represents that bearing-only tracking can be realized when the BAT is in less phase motion than the maneuvering target.
