基于机动检测的自适应IMM目标跟踪算法
|
摘要
针对机动目标跟踪中,单一模型无法描述目标复杂时变的运动过程,提出了一种基于机动检测的自适应交互式多模型(IMM)算法。通过匀速运动模型和基于机动检测的自适应参数Singer模型的组合,不仅能够根据目标的机动状态,实时地调整模型概率,选择与目标运动相匹配的模型,还能够根据目标机动强弱来调整Singer模型的参数。仿真结果表明,相比于单个自适应参数Singer模型跟踪算法和固定参数的交互式多模型算法,基于机动检测的自适应交互式多模型算法有效地提高了机动目标的跟踪精度,实现了机动目标的稳定跟踪。
For maneuvering target tracking,single model can not describe a complex motion process of time-varying target,so an adaptive interactive multi-model(IMM)algorithm based on maneuver detection is proposed in this paper.The algorithm combines the CV model with the adaptive parameter Singer model based on maneuver detection.On the one hand,the model probability can be adjusted in real time according to the maneuver state of the target.On the other hand,the adaptive parameter of Singer model can be adjusted according to the maneuvering strength of target.The simulation results show that,compared with the interactive multi-model algorithm of single adaptive parameter Singer model tracking algorithm and the fixed parameter,the adaptive interactive multimodel target tracking algorithm based on maneuver detection effectively improves the tracking accuracy of maneuvering target,realizes the stable tracking to maneuvering targets.
