摘要
磁通阀式磁传感器的输出存在误差,影响了目标探测的精度。为消除误差,对磁通阀式磁传感器产生误差的机理进行分析,建立误差的数学模型,提出基于最小二乘法的校正方法,根据已测数据实时求解误差,从而进行校正,半实物仿真计算结果说明该方法是有效的。
In order to eliminate error in the output of fluxgate magnetic sensor,which can affect the precision of target detection, the error causing mechanism is analyzed, mathematical model of the error is built and the method of least square correction is proposed. The simulation result shows that the given method is effective.
