摘要
本文针对工程应用背景下,真实环境存在的各种不确定问题,提出一种基于多模型的多目标跟踪算法。通过双门限法判断各量测的使用情况,首先初步确定与量测可能关联的目标,然后对这些目标调用相应的跟踪算法,保证算法的可行性和实时性;由多目标状态估计信息,预测其飞行情况,并根据预测的不同飞行情况切换不同跟踪算法,保证算法的鲁棒性要求。实测数据验证本文的算法具有较好的跟踪性能,适用于工程应用。
A multi-target tracking algorithm based on multi-model is proposed to solve uncertainties in real environment. The algorithm uses dual threshold method to ensure real-time performance and tracking accuracy. The method firstly preliminary determines the targets associated with the measurements, and then tracks these targets. The algorithm also determines the flight conditions according to the target state estimation. Different method are used in accordance with different flight conditions to improve its robust and real time performance. The measured data verifies the efficiency of the algorithm when tracking targets.
