RADIO LOCATION SYSTEM INCLUDING TRANSCEIVER TAGS

摘要

An asset management radio location system uses time-of-arrival differentiation for random and repetitive spread spectrum, short duration pulse 'blinks' from object-attached tags, to provide a practical, continuous identification of the location of each and every object within an environment of interest, irrespective whether the object is stationary or moving. Correlation-based RF processors determine which signals received spatially diverse antennas coupled to tag transmission readers are first-to-arrive signals as transmitted from any blinking tag. An object location processor carries out time-of-arrival differentiation of first-to-arrive transmissions from any blinking tag to determine where the respective object is located within the environment.
