METHOD FOR FORMING A RADIO FREQUENCY RESPONSIVE TARGET AND APPARATUS FOR VERIFYING THE AUTHENTICITY OF SAME |
摘要 |
A method and apparatus for authenticating an object (10) which produces an analog radio frequency signature (36) in response to an interrogating signal (26). The response signal is converted to a code world and is compared to a plurality of valid code words to determine if the object is authentic. The radio frequency responsive targets have a pattern of thin dipoles (510a-510n) which produce a composite analog radio frequency in response to an interrogating signal.
