Weak and Small Group Target Tracking Method Based on Multi-Dimensional Screening of Point Traces

Within the framework of Random Finite Set theory, a trajectory initiation method called Multi-dimensional Screening of Plot (MDSP) is proposed. This method realizes plot screening by constraining the discreteness, signal-to-noise ratio, motion state, and formation configuration of plots. Based on the screening results, different levels are assigned to the plot information, and then high-quality plots are selected to complete the tracking initiation. Simulation experiments verify that the proposed algorithm has better tracking performance than traditional algorithms in dense clutter, with less computational complexity and significantly accelerated response speed to newly born targets. The results show that the proposed method has strong robustness and can achieve accurate tracking of multiple targets under low signal-to-noise ratio.
