【摘要】：航空磁测中飞机的飞行高度通常不是一个平面,曲化平处理可以消除观测面起伏的影响.在进行多参量(例如测量的磁场及其三轴向梯度)测量时,可以研究综合利用测量磁场的多参量的曲化平处理方法.本文通过模型计算,利用梯度转换的法向导数通过边界元方法进行曲化平处理,达到了很好的效果,充分利用磁场梯度反映磁场在各个方向上变化率的作用.对综合利用磁场及其梯度进行曲化平处理给出了一个思路.该方法原理清晰,程序实现简单.
[Abstract]:The flight altitude of aircraft in aeromagnetism is usually not a plane, and the influence of observation surface fluctuation can be eliminated by warping treatment. In the measurement of multi-parameters, such as the measured magnetic field and its triaxial gradient, the multi-parameter warping method of measuring magnetic field can be studied. In this paper, through the calculation of the model, the normal derivative of gradient transformation is used to distort and flatten by boundary element method, and good results are achieved, and the magnetic field gradient is fully used to reflect the change rate of magnetic field in all directions. An idea is given for the comprehensive use of magnetic field and its gradient for warping treatment. The principle of this method is clear and the program implementation is simple.
