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.
In aviation magnetic surveying, the flight altitude of the aircraft is usually not a plane, and the leveling process can eliminate the influence of the fluctuation of the observing surface.When multi-parameter (for example, measured magnetic field and its triaxial gradient) measurements are taken, comprehensive utilization of the measurement magnetic field Of the multi-parameter method of leveling.This paper through the model calculation, the use of the gradient of the normal derivative of the boundary element method for the smoothing of the plane, and achieved good results, make full use of magnetic field gradient reflects the rate of change in all directions Of the role of comprehensive utilization of magnetic field and gradient of the flattened treatment gives a train of thought.The method is clear principle, the program is simple.
