摘　　要：为了探测二战时遗留的地下废弃炸弹,我们开展了磁总场梯度探测模拟实验.在此基础上探讨一些确定磁性体位置和范围的数据处理技术,如自适应化极、垂直二阶导数、三维解析信号及欧拉反褶积反演计算等.将这套数据采集的方法、数据处理的方法运用到实际的废弃炸弹探测中去,取得了一定的效果.研究表明:梯度磁测对于探测地表浅而小的磁性体效果较好、速度快,其数据采取自适应化极方法、垂直二阶导数的方法基本能够确定废弃炸弹的位置及个数,同时采用三维解析信号的数据处理方法能够确定废弃炸弹的方向,采用欧拉反褶积的方法能够确定废弃炸弹的埋藏深度.In order to detect underground waste bomb left over from World War Ⅱ,first of all,we have carried out a total magnetic field gradient detection simulation experiments,secondly,on this basis,explore some of the magnetic body to determine the location and extent of data processing techniques,such as adaptive reduction to the pole,vertical two order derivative,three-dimensional analytic signal and Euler deconvolution inversion calculation,etc,Then use this method of data collection,data processing method to the actual detection of abandoned bombs,and achieved certain results.We believe that the gradient magnetic measurement was a better,faster method for detecting superficial and small magnetic body.And used adaptive reduction to the pole,vertical two order derivative method is basically able to determine the location and number of abandoned bombs,while using three-dimensional analytic signal data processing method to determine the direction of abandoned bombs,using Euler deconvolution method to determine the depth of abandoned bombs.
