Abstract: A ranging device extracts N signal pairs corresponding to N (N>=2) signal strengths excluding one or more signal strengths less than a threshold value among signal strengths of the signal pairs of the first signals and the second signals from the plurality of signal pairs, obtains a reciprocating phase obtained by summing the first phases and the second phases of the first signals and the second signals included in each signal pair for the N signal pairs, and measures a distance to the other device based on the N reciprocating phases and the plurality of frequencies.
