Abstract
A wireless ranging system includes a ranging terminal that transmits a wireless signal including a ranging signal and a communication signal indicating an order of ranging with respect to a first ranging target terminal and a second ranging target terminal, and a first ranging target terminal and a second ranging target terminal that, when receiving the wireless signal, respectively transmits a first response signals and a second response signals consecutively a plurality of times to the ranging terminal. For each time the ranging terminal receives each of the plurality of response signals, the ranging terminal measures an elapsed time from transmission of the wireless signal, and calculates a relative distance between the ranging terminal and the ranging target terminals from a propagation time of each of the plurality of response signals calculated using the elapsed time.
