| 摘 要： | 针对地下铁磁物体埋藏深度大、测量范围受限、各种干扰因素多、与周围介质间磁性差异小难以定位的情况,提出-种分步磁定位方法.首先根据不同深度面上所有测量点的磁场突变值确定铁磁物体顶端所处深度,再利用磁梯度异常和磁场随距离衰减规律实现对磁性体顶端位置的准确定位.实际工程应用表明:该方法对于地下铁磁物体具有定位准确和成本低廉的优势.

| Abstract: | The detection of underground lost iron objects has the difficulties of embedding great depth,too much disturbing factor,little magnetic difference from surrounding medium,a method of steped magnetic orientation was put forward in this paper.The method could determine the embedding depth of lost object's head according wave value of different depth magnetic field from all the measuring point,and then got the lost object peak coordinate position through grads abnormity(its magnetic field varied with distance)... |
