Abstract
An apparatus for remotely detecting metal objects carried by a person includes an antenna and a signal generator coupled to the antenna operable to cause the antenna to emit a first electromagnetic signal to the person at a frequency that is known to be resonant with the human body. The apparatus further includes a data capture device operable to capture response signal energy received by the antenna, the response signal energy being provided from the person in response to the first electromagnetic signal. Processing circuitry for the apparatus is operable to determine whether the response signal energy is indicative whether or not the person is carrying an appreciable amount of metal, based on reference response templates for persons that are known to be metal-free.
