针对光电武器对机动目标跟踪精度较差的问题,在"当前"统计模型的基础上,形成了机动目标"当前"统计模型下强跟踪滤波算法。该算法通过引入强跟踪滤波器的渐消因子,实时调节滤波器增益,增强了系统对突发机动目标的跟踪能力,同时保留了"当前"统计模型跟踪算法对一般机动目标跟踪精度高的特点。仿真结果表明,该算法对机动目标具有较好的跟踪精度和适中的计算复杂度,是一种较好的光电跟踪算法。

Aiming at the problem of optoelectronic weapon used in maneuvering target tracking accuracy,a new adaptive maneuvering target tracking algorithm strong tracking filter-current statistical is presented based on the 'current' statistical model.By introducing a fading factor of strong tracking filter,this algorithm improves the adaptive tracking performance greatly when there is a sudden maneuver,and has the same high precision to track common maneuvering targets as the 'current' statistical model and adaptive tracking algorithm.Simulation results show that the algorithm has a good performance and mezzo computation cost for maneuvering target tracking.
