A method for identifying and ranging a wireless device, comprising: transmitting an original radar signal from a detecting system; in response to the original radar signal, receiving a modulated radar signal at the detecting system, the modulated radar signal being backscattered from an antenna of the wireless device and containing information pertaining to the wireless device, and the modulated radar signal being a frequency offset version of the original radar signal; and, using a processor at the detecting system, determining an identity and a range of the wireless device from the modulated radar signal. |
