Abstract

See full text

A radio frequency (RF) positioning system comprises transceivers, positioning tags, processing units and a computing host. One or multiple positioning tags are attached to a target object being located. When the transceivers first generate and transmit transmission signals, one or multiple tag antennas in the positioning tag receive the transmission signals and transmit back modulated signals. The transceivers then receive and transmit the modulated signals to the processing units. The processing units are configured to obtain received signals, and calculate frequency differences based on the received signals and the transmission signals. The computing host calculates position coordinates of tag antennas based on the frequency differences, and then calculates the orientation of the target object being located according to the position coordinates of the tag antennas.
