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 not reversed is then created.
