BAT弹药对声目标跟踪的仿真研究

Simulation of Acoustic Target Tracking with BAT Munition

BAT子弹药声探测系统是一种运动声阵列,在随弹体做六自由度运动的过程中实时对目标定向。针对运动声阵列仅有角度信息的条件下对目标跟踪问题,用计算机仿真的方法研究了方向误差、高度误差对目标跟踪的影响。首先建立了运动声阵列定向模型,然后在仅有目标角度信息的条件下提出了运动声阵列对目标的跟踪模型,最后用计算机仿真的方法对跟踪模型进行了仿真研究。结果表明:未知弹体抛洒高度时运动声阵列对目标的跟踪需要很高的测向精度,在已知弹体抛洒高度的条件下,则声阵列定向精度能够满足跟踪要求,且跟踪算法简单、收敛较快。

BAT（ Brainpower Antitank） submunition acoustic detection system is a moving acoustic array, which gives real -time localization when it moves with submunition body at 6 degree of freedom. For target tracking with moving acoustic array just gets the angle value, the tracking of maneuvering targets with BAT submunition acoustic detection system is studied by computer simulation, including the effect caused by direction and height error. The paper builds a localization model of moving acoustic array. With target angle value, the target tracking model with moving target array is proposed. The tracking model is studied by computer simulation. The results of the study represents that there must be high localization accuracy when the BAT snbmunition dispersing height is unknown. Once the BAT submunition dispersing height is known, the localization accuracy of moving target array can satisfy the requirement of target tracking, with simple tracking algorithm and quick convergence degree.
