磁场总强度异常的形状受磁化方向(磁倾角和磁偏角)和地磁场矢量的影响.除非磁倾角是90或是0.否则磁异常的中心就不在异常体的正上方通常利用归极换算法消除这种磁倾角和磁偏角的影响使异常中心移至异常体上方许多年前就认识到归极换算法不适用于在低磁纬度地区观察到的异常.这种方法使换算得到的异常有误差,走向也发生偏差.本文提出另一种处理方法来消除磁倾角和磁偏角的影响.这种新方法是将异常换算到磁赤道(磁倾角为0).这是一种滤波方法,重新计算磁场总强度异常,引起异常的物体有如是在水平方向被磁化.经滤波后,异常低值将位于引起异常的物体正上方为了便于解释,使倒相180,则低值异常变成
The general shape of the magnetic field is affected by the direction of magnetization (magnetic dip and magnetic declination) and the geomagnetic field vector unless the magnetic dip is 90 or 0. Otherwise, the center of the magnetic anomaly is not directly above the anomalous body. Method to eliminate the effects of such magnetic declination and magnetic declination to move the anomalous center above the anomalous body Many years ago it was recognized that the polar transformation method was not suitable for anomalies observed in the low magnetic latitude regions. Anomalous error, the trend also deviate.This paper presents another approach to eliminate the influence of magnetic dip and magnetic declination This new method is to convert the anomaly to the magnetic equator (magnetic dip is 0.) This is a filter Method to recalculate the total magnetic field strength anomaly, the object causing the anomaly is, for example, magnetized in the horizontal direction. After filtering, the anomalous low will be located directly above the object causing the anomaly. to make
