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.
