航测磁场自动调平的一种简单方法

A Simple Method for Automatic Leveling Aeromagnetic Survey Data

本文从磁场的调和性出发,提出了一种人为设计切割线进行调平的方法。理论模型和实际资料处理结果表明,该方法可靠,可以满足高精度编图的需要,节约飞行时间,效率高。

In acromagnetic survey,a systematic error is always existed in the measured data along neighbour-Ing prcfiles.This errcr is due to a variety of reasons,such as the variation of flight elevation,the de-viatipn of flight tracks,the change of working condition of instruments,diurnal correction not fullycompensated,etc.,and must to removed in data compilation.In this paper a simple method for autom-atic levelling acromagnetic data is put forward.
