地磁姿态探测器的实时标定方法研究

Real-time calibration method of magnetometer

针对现有的磁差标定方法不适用于导弹地磁姿态探测器实际工作环境的工程问题,提出了一种实时磁差标定与补偿方法,重点解决了异常磁信号野值滤除问题。该方法经转台试验与飞行试验验证,具有实时性好、鲁棒性优、精度高的特点,满足工程应用需要。

Based on the fact that the existing magnetic variation calibration methods are not suitable for missile geomagnetic attitude detectors in the actual working environment, a real-time magnetic variation calibration and compensation method is proposed. The proposed method mainly solves the filtering prob- lem of abnormal magnetic signal outliers. The turntable experiments and flight tests demonstrated good ro- bustness, high accuracy and good real-time performance of this new method. Therefore, the proposed method can meet the requirements of the practical projects.
