Abstract
A ranging method, executed in a ranging device, comprising steps of: obtaining a trip time of a received wireless signal, wherein the received wireless signal is a wireless signal from an object; calculating a statistical value of a rising time of the received wireless signal; when the statistical value of the rising time of the received wireless signal is smaller than the specific value, estimating a distance between the object and the ranging device according to a corrected trip time, wherein the statistical value of the rising time of the received wireless signal corrects the trip time of the received wireless signal to generate the corrected trip time.
