摘　　要：未爆弹通常位于地表之下,探测过程复杂且干扰物较多。激励线圈产生的一次场与未爆弹产生的二次场同时存在,对有效信号产生较大影响。针对这些情况,论文设计了一种新型的基于频域电磁法的单激励多接收传感器,可以完全消除一次场影响并识别未爆弹。通过仿真研究了各接收线圈的响应,验证了未爆弹识别的可行性。最后,搭建实验平台研究了传感器的探测效果,对未爆弹和干扰物进行了区分。Unexploded ordnance is usually located under the surface,the detection process is complicated and there are many interferences.The primary field generated by the excitation coil and the secondary field generated by the unexploded bomb coexist,which has a great impact on the effective signal.Aiming at these situations,this paper designs a new type of single excitation multi-receiving sensor based on frequency domain electromagnetic method,which can completely eliminate the influence of primary field and identify unexploded bombs.The response of each receiving coil is studied by simulation,and the feasibility of UXO identification is verified.Finally,an experimental platform is built to study the detection effect of the sensor,and distinguish between unexploded bombs and interfering objects.
