摘要

利用简易装置探测地下金属目标，并寻求提高探测深度是近年来的热点问题。本文建立了有限元模型，模拟分析了地下金属目标在平面线圈激励下的响应特性。在自定义电磁仪的基础上，比较了不同线圈配置的探测效果，设计了一种新型的正交配置矩形平面线圈传感器，用于探测地下金属目标。该传感器能够探测长40厘米、深1.5米的地下未爆弹药，并能消除小金属碎片的影响。

Underground metal target detection method based on rectangular planar coil and EM instrument

The use of simple devices to detect underground metal targets, and seeking to improve the detection depth is a hot issue in recent years. In this paper, the finite element model is established to simulate and analyze the response characteristics of underground metal targets under the excitation of planar coils. Based on the custom designed electromagnetic instrument(EM instrument), we compared the detection effects of different coil configurations, and a new rectangular planar coil sensor with orthogonal configuration is designed for detecting underground metal targets. The sensor is capable of detecting unexploded ordnance that are 40cm long and 1.5m deep underground, and can eliminate the effects of small metal debris.
