Zusammenfassung: | The present disclosure relates to a radar device, which expands an opening of a receiving antenna by generating a virtual antenna. Specifically, the radar device according to the present disclosure comprises: an antenna unit including a first receiving antenna including at least one receiving channel, each receiving channel being disposed at a first interval, and a first transmitting antenna including at least one transmitting channel, each transmitting channel being disposed at a second interval; a transceiver for transmitting a transmission signal through a transmission antenna and receiving a reflection signal reflected from an object through a reception antenna; and a control unit which obtains information about the object by processing the reflected signal received through the receiving antenna.
