Abstract
In an in-vehicle radar device, as a vertical azimuth which is an azimuth of a target in a direction perpendicular to a ground surface, a real image vertical azimuth which is an azimuth of a real image existing above ground is calculated from a reflected wave generated when a transmission signal transmitted from a transmission antenna is reflected from the target, and a virtual image vertical azimuth which is an azimuth of a virtual image existing underground is calculated from 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. Next, in the in-vehicle radar device, an angle difference between the real image vertical azimuth and the virtual image vertical azimuth is calculated, and a height of the target from the ground surface is calculated using the calculated angle difference.
