Abstract
A method for tracking objects within a three-dimensional capture zone includes placing at least four sensors around the capture zone. A stationery reference tag is placed within the capture zone. Tags are coupled to objects to be tracked in the capture zone. Signals are periodically transmitted from the reference and object tags. These signals are received and the identification code, and code phase and carrier phase measurements are extracted. The code phrase and carrier phase measurements are processed to determine the position of each object tag with respect to the reference tag at each sampling instant.
