Abstract
A method and apparatus for detecting an object comprising a radio frequency transmitter for transmitting a radio frequency signal towards an object; an acoustic signal transmitter for transmitting an acoustic signal capable of causing intermittent contact of conductive and/or semi-conductive junctions of the object; and a radio frequency receiver for receiving the radio frequency signal after the radio frequency signal is reflected from the object, where the received radio frequency signal has been altered by the intermittent contact of conductive and/or semi-conductive junctions of the object.
