关于组合导航系统中的熵理论

Research on Entropy Theory in Integrated Navigation System

从信息论中的熵理论出发,论述了组合导航系统中熵的基本模型,研究了组合导航系统中的信息测量、信息融合等同题。提出了导航信息融合率的概念,引伸了组合导航系统中关于平均互信息的两条重要定理,并指出了它们在理论研究和实际应用的指导意义。结果和实例表明:熵理论从本质上刻画了导航信息的信息流动和变化,熵是衡量组合导航系统的信息融合性能的一个重要特征量。

In view of information entropy theory, the basic entropy model for integrated navigation system is established, and. information measurement and information fusion are discussed based on the model. Also, the concept of the fusion rate of navigation information and two important theorems relative to the average interactive information are proposed at the first time. Then, theirs directive significance in theoretical study and practice is pointed out. The research result shows entropy theory is characterized the flow and change of navigation information in essence,it's of the importance as entropy as a measure for integrated navigation system.
