Title: Short-range radio-telemetry for electronic identification, using modulated RF backscatter

Abstract

An electronic identification system which uses modulated backscatter from an rf beam-powered tag is described. A subcarrier is used in the return signal format to allow separation from the background clutter and to allow use of a novel method to avoid rf phase problems. The system is being developed for livestock, such as dairy cattle, and reports the animal's temperature and location. A block diagram of the telemetry systems is shown. (TFD)
