- Abstract:
-
To address the issues of difficult measurement set partitioning and inaccurate estimation of the number of targets in extended target tracking, we suggest a grid clustering measurement set partitioning approach for extended target tracking. Firstly, the current moment measurement is classified into two categories based on the time-space correlation between the targets: survival-target measurement and newborn-target measurement. Then, an improved fuzzy C-means algorithm and an improved grid clustering algorithm are derived for the Gaussian mixture probability hypothesis density filter and the extended target Gaussian mixture probability hypothesis density filter, respectively, which are employed to separate the viable target set and the new target set. The simulation results show that the proposed techniques can accurately divide the measurement set, effectively complete the extended target tracking, and avoid the missed and over-checked measurements.
