摘　　要：在航空磁测目标识别过程中,磁性物体可以用磁偶极子模型来表示,应用Matlab软件中二维双线性插值的方法对磁性目标磁偶极子模型空间磁场的剖面截取进行了仿真,得到了磁测剖面曲线和平面等值线图两种仿真结果。这里提出的平面等值线图剖面截取方法,能够提取出任意方向的磁测曲线,此方法计算简单、操作性好,可应用在各种测量数据等值线图的剖面提取中。In the process of target identification in aeromagnetic survey, magnetic objects can be indicated by magnetic dipole mode. We acquired two results with the simulation of the space magnetic field caused by magnetic dipole mode of mag- netic objects by the 2D bilinear interpolation method. One is the magnetic curve and the other one is the magnetic contour map. We presented a method to intercept the profile of the magnetic contour map, which could extract the magnetic curve in all directions. In addition, this method is very simple and easy to operate, which can he used to intercept the profile of the contour map in all measurements.
