摘　　要：三分量磁通门传感器的不水平问题会对磁测量带来不利影响。提出了一种校正磁传感器姿态不水平的方法,通过构造磁传感器的测量模型,分析了姿态不水平对磁测量的影响,对角度旋转下的磁传感器的测量数据进行校正处理,采用DE算法进行求解磁传感器的水平误差角,获得了较准确的磁场测量值。仿真和实验证明了该方法的正确性和有效性,经校正后磁传感器测量精度得了较大幅度提高,对改善磁传感器的应用性能有重要的指导意义。The non-horizontal problem would have an negative effect on measurement of thriaxial fluxgate magnetometer.A method is proposed for correction of thriaxial magnetometer.The mathematic model is constructed to calculate the horizontal angles and the non-horizontal effect is analysed for magnetic measurement.The measured data is got in evenly angle and calibrated.DE algorithm is used to calculate the horizontal angle of magnetometer,and accurate magnetic value can be got.The simulation and experiment show that the method is correct and effective,and the precision of the magnetic sensor is greatly improved after correction,which has important guiding significance for improving the application performance of thriaxial magnetometer.
