摘要:

为了解决杂波和漏检下多目标的联合跟踪与分类问题,提出了模型类型匹配概率假设密度(probability hypothesis density,PHD)滤波器,同时将其与多传感器的可转移信度模型(transferable belief model,TBM)框架相结合,并用多个运动学雷达和粒子滤波递推实现。该算法对飞行器的先验信息进行估计,从而替代了属性传感器。在预测阶段,根据模型和类型对PHD滤波器进行粒子匹配;传感器得到观测结果后进行粒子权重的更新;再根据粒子对应的权重得到目标的后验状态模型类型分布;这些PHD滤波器可以同时得到目标的状态和类型;结合TBM和航迹粒子标签算法,得到多个传感器的融合结果。仿真表明,本文提出的模型类型匹配PHD滤波器的性能比传统多模型PHD滤波器更精确,同时多传感器的TBM框架也全面提升了算法的性能。

Abstract:

To solve the multi-target joint tracking and classification under clutter and miss detection, the model-class-matched probability hypothesis density (PHD) filter is proposed and combined with the transferable belief model (TBM) framework of multiple sensors, and it is recursively implemented by multiple kinematic radars and particle filtering. In our algorithm, the priori information of aircraft is estimated to replace the attribute sensor. At the prediction stage, the particles of the PHD filter are matched by model and class; the particle weights are updated after the sensors receive the measurement information; then, the targets’ posterior statemodelclass distribution is got by the corresponding weights of the particles; the targets’ state and class can be obtained simultaneously by these PHD filters; finally, by integrating TBM and the track particle labeling algorithm, the fusion result of multiple sensors is acquired. Simulations indicate that the performance of the proposed model-class-matched PHD filter is much better than that of the traditional PHD filter, and in the meantime the TBM framework of multiple sensors also improves the performance the proposed algorithm.
