Claim:
1. A radar device comprising: a vertical azimuth calculation unit which calculates, as a vertical azimuth which is an azimuth of a target in a direction perpendicular to a ground surface, an azimuth of a real image existing above ground from a reflected wave generated when a transmission signal transmitted from a transmission antenna is reflected from the target, and an azimuth of a virtual image imaginarily existing underground using a reflected wave generated when the transmission signal transmitted from the transmission antenna is reflected from the target and reflected again from the ground surface; an angle difference calculation unit which calculates an angle difference between the azimuth of the real image and the azimuth of the virtual image which are calculated by the vertical azimuth calculation unit; and a height calculation unit which calculates a height of the target from the ground surface, using the angle difference calculated by the angle difference calculation unit.
