Abstract:
A distance measuring device according to an embodiment includes a first device including a first transceiver configured to transmit a first known signal and a second known signal and receive a third known signal corresponding to the first known signal and a fourth known signal corresponding to the second known signal, a second device including a second transceiver configured to transmit the third known signal and the fourth known signal and receive the first and second known signals and a calculating section configured to calculate a distance between the first device and the second device on a basis of phases of the first to fourth known signals, and the first transceiver and the second transceiver transmit/receive the first and third known signals one time each and transmit/receive the second and fourth known signals one time each, performing transmission/reception a total of four times.

Claim (Index 8):
A distance measuring device that calculates a distance between a first device and a second device, at least one of which is movable, on a basis of phases of first to fourth known signals transmitted at\n a plurality of carrier frequencies, wherein\n the first device includes:\n a first reference signal source; and \n a first transceiver configured to transmit the first known signal corresponding to a first carrier frequency and the second known signal corresponding to a second carrier frequency different from the first carrier frequency, and receive the third known signal corresponding to the first carrier frequency and the fourth known signal corresponding to the second carrier frequency, using an output of the first reference signal source, \n \n the second device includes:\n a second reference signal source configured to operate independently from the first reference signal source; and \n a second transceiver configured to transmit the third known signal corresponding to the first carrier frequency and the fourth known signal corresponding to the second carrier frequency and receive the first known signal and the second known signal, using an output of the second reference signal source, \n \n the first or second device includes a first phase detector configured to detect phases of the third and fourth known signals received by the first transceiver, \n the first or second device includes a second phase detector configured to detect phases of the first and second known signals received by the second transceiver, \n the first or second device includes a calculating section configured to calculate a distance between the first device and the second device on a basis of a phase difference between the third and fourth known signals detected by the first phase detector and a phase difference between the first and second known signals detected by the second phase detector, and \n the first transceiver and the second transceiver transmit/receive the first known signal and the third known signal corresponding to the first known signal one time each and transmit/receive the second known signal and the fourth known signal corresponding to the second known signal one time each, performing transmission/reception a total of four times, \n wherein the first transceiver transmits a fifth known signal corresponding to a third carrier frequency different from the first carrier frequency and the second carrier frequency and receives a sixth known signal corresponding to the third carrier frequency, using an output of the first reference signal source, \n the second transceiver transmits the sixth known signal and receives the fifth known signal using an output of the second reference signal source, \n the first transceiver and the second transceiver transmit/receive the fifth and sixth known signals one time each after transmitting/receiving the first and third known signals one time each and transmitting/receiving the second and fourth known signals one time each, and \n the second transceiver receives the fifth known signal twice at a predetermined interval in transmission/reception of the fifth and sixth known signals one time each.
