Abstract
A ranging apparatus of an embodiment is a ranging apparatus adopting communication type ranging by a phase detection scheme. The ranging apparatus including: a transmitting circuit configured to be able to transmit by a plurality of channels used for data communication and configured to transmit a transmission signal obtained by modulating transmission data; and a control circuit configured to control the transmission circuit to cause a plurality of continuous waves having mutually different frequencies to be generated in a same channel as continuous waves used for ranging by the phase detection scheme.
Claims6
A ranging apparatus adopting communication type ranging by a phase detection scheme, the ranging apparatus comprising:
- a transmitting circuit configured to be able to transmit by a plurality of channels used for data communication and configured to transmit a transmission signal obtained by modulating transmission data;
- and
- a control circuit configured to control the transmission circuit to cause a plurality of continuous waves having mutually different frequencies to be generated in a same channel as continuous waves used for ranging by the phase detection scheme.
A ranging method adopting communication type ranging by a phase detection scheme, the ranging method comprising:
- generating continuous 1s and continuous 0s as transmission data;
- and
- providing the continuous 1s and the continuous 0s to a transmitting circuit configured to FSK-modulate transmission data to transmit a transmission signal to cause a plurality of continuous waves having mutually different frequencies in a predetermined channel among a plurality of channels used for data communication to be generated as transmission signals for ranging.
