error covariance
Examples
- A recursive algorithm of error covariance matrix of moving horizon estimation
滚动时域估计中先验估计误差协方差阵的递归算法 - When the observation noise is temporal correlation , kalman filter will not be able to achieve optimization , and its covariance matrix will be wrong
在观测噪声不满足时间不相关的假设情况下，卡尔曼滤波将达不到最优滤波效果，并且其误差协方差阵也是错误的。 - By the definition of incremental error quaternion in the propagation equation of the full rank covariance matrix is derived , consequently the singularity of the covariance matrix caused by the constraint on the quaternion normalization is maintained
并且通过定义增量误差四元数,推导出满秩空间中误差协方差阵的传播方程,解决了由于四元数正交约束所造成的协方差阵奇异性问题。 - Some modeling of maneuvering target tracking is introduced in this thesis , and current statistical model is used as a basic target model . the arithmetic of kalman filtering based on the model is listed . on the foundation of state vector optimal estimation error matrix theory , the arithmetic of optimal estimation is presented , and target tracking simulation is taken
本文首先介绍了几种常用的机动目标跟踪模型,并把现在较为常用的“当前”统计模型作为本文研究的目标模型,并列出了基于该模型下的卡尔曼滤波算法;此外,在状态矢量最优加权估计理论的基础上,引入了目标状态最优估计误差协方差矩阵,提出了一种最优加权估计算法,并进行了目标跟踪仿真。
