Detection and classification of Buried Metallic Objects

Metal locators are widely used for locating metallic objects at archaeological sites. The<br>process is identical to that used for the task of identifying land-mines and un-exploded<br>ordnance (UXO). There has been a major effort to develop new metal locators, both to<br>improve detection and more importantly to identify the size, shape, and metal content of the<br>object and to discriminate against scrap metal and the effects of magnetic and electric<br>inhomogenieties in the ground. The advances being made in this area will naturally lead to<br>significant improvements for the application of electromagnetic methods in archaeology.
