| 摘 要： | 在组合导航融合算法中引入证据理论对导航信息进行决策应用,推导出2个传感器信息融合后的结论,并且通过仿真实验得出计算结果。证据理论判断公式在处理具有证据冲突的相关信息时引入不确定熵的概念。证据理论算法通过不确定熵在加权合成算法和乘权合成算法之间作适度的折中判断。这种改进的证据理论方法可以分析组合导航信息融合算法中存在的问题,并给出最后的决策执行命令。

| Abstract: | The paper uses the D-S evidence theory in the navigation fusion algorithm to make decisions. The D-S evidence theory is used to deduce some conclusions which are calculated after the two sensors＇ information fusion, and the simulation test proves the result. The formula of the D-S evidence theory uses the uncertain entropy to deal with the conflicting information. The D-S evidence theory uses the uncertain entropy to make moderate judge between the weighting algorithm and the multiplication combining algorithm. This improved D-S evidence algorithm can discover the problem in the integrated navigation information fusion and make the final decision. |
