用于平台连续瞄准和校准的卡尔曼滤波器

A Kalman filter for continuous alignment and calibration of the inertial platform

本文为提高制导精度,讨论了用于惯性平台的连续瞄准、校准的卡尔曼滤波器,介绍平台系统和加速度表的误差模型、参数辨识的卡尔曼滤波方法及重力残数加速度表校准原理。

In this paper, in order to raise the guidance accuracy, a kalman filter for con- tinuous alignment and calibration of the inertial platform is described. Then introdace the er- rors model of a platform system and accelerometer, Kalman filtering methods for paramatric identification and the calibration principle of gravity measurement residue of accelerometr.
