传统的信息融合框架一般采用单向融合模式,不利于信息的累积、认知和反复利用,因而信息利用率低,限制了信息融合效果。反馈式融合采用由融合输出向输入的反馈机制,在抑制干扰、提高目标检测效果和精度等方面有较好的表现,而且融合过程的控制也更为灵活,在提高系统信息利用率的同时也具备了智能化信息处理的潜能。因此,反馈式融合结构在近年来得到了广泛的关注。对反馈融合方法在传统信息融合框架各层级中的应用进行了研究。结合国内外发展状况,总结了一些信息反馈融合新的思路和方法,对其中存在的一些问题进行了描述,并对下一步的发展和应用方向进行了展望。
The traditional information fusion framework generally adopts unidirectional fusion mode, which is not conducive to the accumulation, cognition and reuse of information. Therefore, the low information utilization limits the effect of information fusion. The feedback fusion adopts the feedback mechanism from the fused output to the input, has good performance in suppressing interference, improving the target detection effect and accuracy, and the control of the fusion process is also more flexible. While improving the utilization of system information, Have the potential of intelligent information processing. Therefore, the feedback fusion structure has received widespread attention in recent years. The application of feedback fusion method in all levels of traditional information fusion framework is studied. Combining with the development at home and abroad, this paper summarizes some new ideas and methods of information feedback fusion, describes some of the existing problems and prospects the development and application of the next step.
