Beschreibung
Zusammenfassung:	A radar device includes: reception array antennas each including virtual antennas constructed from plural transmission antennas and plural reception antennas; and a transmission control unit which controls transmission waves transmitted from the transmission antennas, the plural transmission antennas include: a first transmission antenna group having at least two of the transmission antennas that are spaced from each other by a prescribed first interval; and a second transmission antenna group having at least one of the transmission antenna that is spaced, by a prescribed second interval, from a synthesized antenna that is the first transmission antenna group as regarded as a single antenna; and the transmission control unit is capable of switching between: a first mode and a second mode as defined herein.
