多传感器目标检测的模糊信息融合技术研究

Research on Fuzzy Information Fusion of Multi-sensor Detecting Systems

在多传感器目标检测系统设计中 ,往往需要对传感器虚警率和检测率进行数学描述 ,原来的经典概率值不能对这种本性不确定的量进行充分描述 ,利用模糊集合对这种不确定性进行模糊建模更符合所研究物理现象的客观事实。文中将模糊集合理论应用到分布式多传感器检测系统的一种信息融合算法中 。

It is needed to describe the probability of detection and probability of false alarm mathematically in the design of a multi sensor detecting system.The classical probability can't describe uncertainty associated with these two probability,Whereas it accord more with the fact of physical phenomenon to use the fuzzy sets to establish the model of uncertainty .In this paper,the principle of fuzzy sets is introduced to the algorithm of data fusion which is usually used in the distributed multi sensor detecting system and an advanced information fusion algorithm is obtained.
