| 摘 要： | 在多目标信息融合中，通过数据关联判断来自不同传感器的数据是否代表同一个目标，传统数据关联一般采用联合概率数据关联算法，单纯依靠状态量测且计算复杂。而基于灰色关联的概率数据关联算法，能够利用目标的多个特征信息进行数据关联，且计算简单准确。特征信息一般由专家主观判断给出。提出了基于熵权的灰色关联概率数据关联算法，由量测数据自适应的给出各特征的权重系数，不依赖于专家。仿真表明，该关联算法具有很好的工程实用性。

| Abstract: | Data association is used to jude whether the data from different sensors stand for the same target in the multitarget information fusion.Tradition data association always take the joint probabilistic data association(JPDA) algorithm as the priority means which depends only on the state measurement,so the computation is complex.A PDA algorithm used based on gray correlation analysis not only calculates with multiple features of the target,but also is easy.Compared to the weight factor of feature given by sub... |
