摘要
本文针对非线性多传感器系统的状态估计问题，提出了准分层融合算法。文中，首先推出了准分层融合估计式，而后说明其算法，并讨论其性质，最后，给出其工程上可实现的结构框图。理论结果表明，该算法可用作多传感器的广义卡尔曼滤波。实际需要表明，该算法比文献￣［１］中线性系统的分层融合法更有应用前景。
An algorithm for quasihierarchy fusion of data,which is used to solve the nonliner problems in the multisensor system,is introduced in this paper.First,the quasihierarchy fusion for formulas of the state estimation are deduced.Second,their computation method is given and their characterictics are discussed.Finally,the realization architecture for the above algorithm is also pres-ented.The theoretical results have proved that the algorithrn can be considered as the generalized Kalman filter of multisensor The practical needs have shown that the algorithm has a more bright future in the application than the algorithm in￣[1] for the hierarchy fusion in the liner system does.
