摘要

介绍了线性时变系统的局部可观测矩阵。该矩阵可用于可观察性分析;对于线性时变系统，它比通常的可观察性语法更容易使用。将该矩阵应用于地形辅助惯性导航系统，揭示了系统在地形性质方面的可观测性。给出并讨论了模拟协方差分析的结果。

Local observability matrix and its application to observability analyses

A local observability matrix for a linear time-varying system is introduced. The matrix is useful for observability analysis; it is much easier to use than the usual observability grammian for linear time-varying systems. The matrix is applied to a terrain-aided inertial navigation system to reveal the observability of the system in terms of the nature of the terrain. Results of a simulated covariance analysis are presented and discussed.<>
