一种基于差分接收的电磁感应阵列探头的设计与实现

An EMI array sensor based on differential reception

为了有效提升车载或无人平台电磁感应探测系统的综合性能,针对国内现有阵列探头技术存在土壤适应性差、定位精度低、抗干扰能力弱等不足,提出一种基于差分接收的阵列式电磁感应阵列探头设计方案。该方案总体采用单发射线圈内部水平排列多个接收线圈的结构形式,接收线圈采用双D形平衡式线圈实现差分接收,使系统在土壤适应性、定位精度及抗干扰能力等性能方面得到提升,从而有效提高未爆弹的探测效率。模拟雷场的实验结果表明,本文设计的阵列探头可实现对未爆弹的探测和定位。

This study proposes an EMI array sensor based on differential reception,which can effectively improve the comprehensive performance of the EMI system on a vehicle or robot in terms of soil adaptability,positioning accuracy,and anti-interference ability.The EMI array sensor consists of a large transmitting coil and multiple receiving coils,which are horizontally arranged in the transmitting coil.Meanwhile,the receiving coils are a kind of double-D coils to realize differential reception.In this manner,the detection efficiency of unexploded ordnances(UXO)can be effectively improved using the EMI array sensor.The simulated minefield detection test results show that the array sensor proposed in this study can be used for UXO detection and positioning.
