摘要

针对现有的多目标跟踪(MTT)算法在强杂波环境下会出现严重的性能衰退,利用目标的幅度及多普勒特征,基于随机有限集(RFS)理论,提出了一种幅度及多普勒信息辅助的δ广义标签多伯努利(ADI-δ-GLMB)滤波器。首先,利用幅度及多普勒信息对目标状态进行扩展,在此基础上建立了新的量测似然函数。然后,基于δ-GLMB滤波器框架推导了新的更新方程。最后,进行仿真验证,结果表明:强杂波下,ADI-δ-GLMB滤波器跟踪性能明显优于δ-GLMB滤波器,估计精度及稳定性更高,且计算量更低;同信息辅助的概率假设密度(PHD)、多目标多伯努利(MeMBer)滤波器相比,ADI-δ-GLMB滤波器状态估计精度更高。

Abstract

To address the severe performance degradation of the existing Multi-Target Tracking (MTT) in high clutter environment, a novel Amplitude and Doppler Information assisted δ-Generalized Labeled Multi-Bernoulli (ADI-δ-GLMB) filter is proposed based on the theory of Random Finite Set (RFS). Firstly, the amplitude and Doppler information isintroduced to expand the target state, and a new function of measurement likelihood is established on this basis. Then, a new update equation is deduced based on the framework of the δ-GLMB filter. Finally, the simulation results show that the tracking performance of the proposed ADI-δ-GLMB filter is significantly better than that of the standard δ-GLMB filter, displaying higher estimation accuracy and stability, and a lower computational cost in dense clutter environment. In addition, the estimation accuracy of the proposed ADI-δ-GLMB filter is higher than that of the information assisted Probability Hypothesis Density (PHD) and Multi-target Multi-Bernoulli (MeMBer) filter.
