METHOD AND SYSTEM FOR DISTANCE DETERMINATION OF RF TAGS

摘要

The present invention relates to a method and system (10) for distance determination of RF tags (4) and its applications, based on measuring the round trip delay, avoiding deterministic collisions between a plurality of wide band response signals transmitted by the tags (4) by adding a pseudo-random time delay to the wide band response signal, and iteratively reducing the collision probability between plurality of wide band response signals.
