- one terminal 20 emits a sine wave at a frequency f [Hz].
- the radio wave emitted from the terminal 20 travels toward the base station 10 (Reflector), which is another radio device located a distance D [m] away.
- the base station 10 (Reflector) receives radio waves emitted from the terminal 20 (Initiator), and at that time receives a sine wave whose phase has been rotated according to the distance D [m].
- the phase of the sine wave at the time it is transmitted from the terminal 20 (Initiator) is 0 [rad]

- the base station 10 (Reflector) When the emission of radio waves from the terminal 20 (Initiator) to the base station 10 (Reflector) is completed, the base station 10 (Reflector) then emits radio waves to the terminal 20 (Initiator). At this time, the base station 10 (Reflector) emits a sine wave rotated by ⁇ [rad] in advance. Therefore, the phase of the sine wave received by the terminal 20 (Initiator) is the phase rotated by the distance D [m] with respect to the phase of ⁇ [rad] emitted by the base station 10 (Reflector), that is, 2 ⁇ [ A sine wave whose phase has been rotated by [rad] will be received.
- the terminal 20 (Initiator) since it is known in advance that the terminal 20 (Initiator) first emitted a sine wave with a phase of 0 [rad], the radio waves are sent back and forth between the terminal 20 (Initiator) and the base station 10 (Reflector). It can be seen that the phase rotates by 2 ⁇ [rad]. Therefore, on the terminal 20 (initiator) side, the one-way phase rotation amount can be calculated as ⁇ by halving the phase rotation amount of the observed sine wave from the base station 10 (reflector).

- the distance measurement unit 102 can also subtract the length of the wireless cable L104 and the length of the wireless cable L206 of the terminal 20 from D in equation (2). This suppresses an error in the total length of the wireless cable L104 and the wireless cable L206.
- the length of the wireless cable L206 can be obtained in advance from the terminal 20 through wireless communication.
- phase becomes larger than the phase of the direct wave. For example, if a plurality of 2 ⁇ [rad] are measured between the terminal 20 (Initiator) and the base station 10 (Reflector), it is possible to select the smallest 2 ⁇ [rad]. This makes it possible to generate the group delay ⁇ of only the direct wave.
