摘要
从理论上给出了提高卡尔曼滤波器收敛速度和精度的一种方法.利用卡尔曼滤波递推公式证明了有用观测信息的增加,即观测增强有助干抑制量测噪声,从而提高卡尔曼滤波器的收敛速度和精度,为在捷联惯导(SINS)动基座快速传递对准技术中经常使用的抑制量测噪声的方法提供了理论依据.通过积分匹配、双积分匹配以及机动运动强度变化的仿真例子验证了方法的有效性.
A theory approach to increasing Kalman filter converging speed and accuracy is put forward. It is pointed out that increasing useful observing information, that is observability enhancing, helps to suppress measure noise and increase Kalman filter converging speed and accuracy. It provides a theory support for the methods applied to SINS rapid transfer alignment on moving base. The simulation examples show that this approach is efficient.
