基于分段序列离散度的异步航迹关联算法

doi:10.7527/S1000-6893.2020.23694

Abstract

Abstract: To solve the problem of asynchronous unequal rate track association, this paper proposes an asynchronous track-to-track association algorithm based on discrete degree of segmented sequence. A discrete information measurement of segmented and mixed track sequence is defined, and the segmentation rules of track sequence with unequal lengths are presented. The association determination is performed via calculation of the discrete degree and adoption of the classical assignment method. In view of the ambiguity problem, a secondary inspection link is established. Compared with traditional algorithms, this algorithm requires no time alignment and is not affected by noise distribution. The simulation results show that the algorithm can maintain stable association effect with high accuracy under the conditions of asynchronous track and different sensor sampling rates. Furthermore, it can effectively distinguish complex situations such as track crossing, bifurcation and merging, exhibiting clear advantages.
