| 摘 要： | 三分量磁通门传感器是磁场测量中普遍使用的仪器,磁传感器的测量坐标系由三个正交的螺线管确定,但是这种传感器的测量坐标系的水平坐标平面通常不平行于其基座水平面,这样一个倾斜的测量坐标系会带来测量误差.为了解决这一问题,提出了采用共轭梯度优化的方法求解水平修正参数,进而修正由坐标系不水平带来的误差的方法.采用该方法计算了某一三分量磁通门传感器的水平修正参数,经过修正后的传感器,其性能得到了明显改善.

| Abstract: | Triaxial fluxgate magnetometer is an instrument often used in the measurement of magnetic field. The coordinate system of a magnetometer is determined by three orthogonal solenoids, but the horizontal coordinate plane of such a coordinate system is not always precisely parallel to the plane of its base plane. A leaning coordinate system will lead to some errors. In order to solve the problem, a method of conjugate gradient optimization was applied to find the horizontal error angles. An experiment was done to calculate horizontal error angles of a triaxial fluxgate magnetometer. The performance of the sensor is improved greatly after the horizontal calibration. |
