摘要： 航磁补偿飞行中，飞机姿态变化产生的磁场严重影响航磁数据精度。为了补偿飞机产生的磁干扰，基于Tolles-Lawson方程建立补偿模型，其中关键是计算方向余弦值；采用Leach提出的基于三轴磁通门解算方向余弦方法建立航磁补偿系统；依据当地水平坐标系与飞机坐标系之间的旋转关系，建立了机载三轴磁通门数据的理论模型解算方向余弦，从而验证了该补偿方法的有效性。将该方法运用到云南某实验场地的航磁补偿数据中，并选择标准差作为评价补偿效果的指标，得到补偿质量满足规范要求，说明基于磁通门估计的航磁补偿方法是有效的。

关键词: 飞机磁干扰, 磁干扰补偿, 方向余弦, 三轴磁通门, 理论模型

Abstract: In aeromagnetic compensation flight, the magnetic field generated by aircraft attitude change seriously affects the accuracy of aeromagnetic data. In order to compensate the magnetic interference generated by aircraft, a compensation model is established based on Tolles-Lawson equation, the key of which is to calculate the value of direction cosine. Leach's directional cosine method based on three-axis fluxgate is used to build the aeromagnetic compensation system. According to the rotation relationship between the local horizontal coordinate system and the aircraft coordinate system, the theoretical model of airborne three-axis fluxgate data is established to solve the direction cosine. The method is applied to the aeromagnetic compensation data of a test site in Yunnan, and the standard deviation is selected as an indicator for evaluating the compensation effect. The compensation quality satisfies the industry standards, which verifies the effectiveness of the aeromagnetic compensation method based on fluxgate estimation.

Key words: aircraft magnetic interference, magnetic interference compensation, direction cosine, three-axis fluxgate, theoretical model
