组合导航信息融合技术研究

Information Fusion of Integrated Navigation System

分析了联合卡尔曼滤波算法中参考系统、主滤波器以及局部滤波器的特点，给出了组合导航系统的联合滤波算法的具体描述，提出了一种基于广义特征值分解的自适应信息分配策略，该结果表明，采用组合导航信息融合技术在工程实践上确实可以解决根据组合导航局部滤波器性能随时调整信息分配策略的问题。

For the sake of combination that keep integrated navigation partial filter function variety from integrating the problem adjust the information allotment, the paper analyzed in association with consults in the Kalman filter a calculate way the characteristics between system, main filter and partial filter, give the integrated navigation system of in association with the describes of federated filter algorithm in a specific way, putting forward a kind of according to the broad sense characteristic value resolves of from orientation information allotment strategy, that result expresses, adopting the integrated navigation information fusion technique to practice in the engineering top assuredness can resolve to integrated navigation the partial filter function to adjust the problem that information assign the strategy at any time according to the combination.
