Abstract
Object detecting and classifying apparatus is disclosed wherein signals, ulting from electromagnetic coupling between a search unit and an elongated, narrow, conductive object, are processed so as to provide automatic indication of detection of an object of the type mentioned. The apparatus discriminates against false indications from background and spurious signals and against signals from objects of other types by utilizing search unit means that produces successive signals having predetermined time relation to one another only when an object of the class sought is crossed, together with signal processing logic means responsive thereto, and recording and/or indicating means responsive to the logic means.
