超宽带探地雷达是近年来迅速发展起来的一种高新无损检测技术，可对地下目标进行高分辨率成像，但很难直接判断目标是金属或非金属的，而且无法得到准确的探测深度。针对地下目标材质识别和获取准确探测深度的需求，研制了一种将电磁感应与超宽带雷达相结合的新的探测系统。该系统可以直接分辨金属和非金属目标，并能反演出介质的介电常数，从而得到目标的准确深度。将该探测系统在测试模型上进行了实验，取得了很好的效果。

Ground penetrating radar (GPR)is a recently developed technology for nondestructive examination (NDE). It can be used to image the buried objects with high resolution.But GPR can’t directly tell an object metallic or not, and can’t give accurate depth of detected object.We developed a device based on electromagnetic induction (EMI)and GPR.This device can discriminate metallic object from others easily and give its accurate depth.We tested the device on a modal and got a satisfied result.
