摘要:

群分割技术作为群目标跟踪技术的首要环节,其处理结果直接影响后续整个数据处理过程的效果。在深入研究目前已有的群分割技术的基础上,提出了一种基于坐标映射距离差分的快速群分割算法。首先将量测集的二维信息分解为两组坐标映射距离的一维信息,进而分别进行排序和分群处理,从而减小了算法的时间复杂度,最后将分别获得的两组预备群进行取交关联,得到最终的分割群。通过与3种传统算法在时间复杂度上的理论分析与比较,该方法在大视场回波稀疏条件下具有显著的效率优势。经过多场景的仿真分析表明,该算法的处理效能显著高于传统算法,且对复杂动态场景具有较好的鲁棒性。

Abstract:

As a primary technology of group targets tracking, the result of group segmentation is the key to the outcome of the entire data processing progress. Based on the stateofart researches, a fast algorithm of group segmentation based on coordinates transformations and distance differentiations is proposed. Firstly, the twodimension information of acquired sets is decomposed into two onedimensional information of coordinate distance. Then, the sets are sorted and segmented, which make time complexity reduced. Finally, the final segmentation group is obtained by extracting the intersection of two underprocessed groups. Compared to three traditional methods in theory analysis of time complexity, the proposed method is more effective especially under the condition of large field of vision with sparse radar echoes. The simulation results of multiscences show that, the proposed algorithm is much more efficient than the traditional methods, and has excellent robustness to dynamic scenes.
