A method and apparatus to remove human features utilizing at least one
transmitter transmitting a signal between 200 MHz and 1 THz, the signal
having at least one characteristic of elliptical polarization, and at
least one receiver receiving the reflection of the signal from the
transmitter. A plurality of such receivers and transmitters are arranged
together in an array which is in turn mounted to a scanner, allowing the
array to be passed adjacent to the surface of the item being imaged while
the transmitter is transmitting electromagnetic radiation. The array is
passed adjacent to the surface of the item, such as a human being, that
is being imaged. The portions of the received signals wherein the
polarity of the characteristic has been reversed and those portions of
the received signal wherein the polarity of the characteristic has not
been reversed are identified. An image of the item from those portions of
the received signal wherein the polarity of the characteristic was
reversed is then created.
