Abstract

In a radar device (), when a distance determined based on a range of fields of view required of the radar device () is defined as a distance d, transmission antennas (Tx) are arranged side by side with an antenna interval that is larger than the distance d in a first array direction, which is perpendicular to an emission direction of a transmission signal, reception antennas (Rx) are arranged side by side at antenna intervals that are larger than the distance d in a second array direction, which is parallel to the first array direction, and the transmission antennas (Tx) and the reception antennas (Rx) form virtual reception antennas (VR), which have an antenna arrangement including at least one part in which a virtual antenna interval is the distance d or less.
