Abstract: A method for calculating an altitude of a target through an apparatus for calculating an altitude of the target, which comprises a plurality of MIMO radar virtual antennas, may comprise: receiving electromagnetic waves reflected from the target through a pair of virtual antennas classified into an upper antenna and a lower antenna and alternately arranged in two columns linearly; obtaining range information and phase information of the target from the pair of virtual antennas by analyzing the electromagnetic waves; and calculating altitude information of the target from position information of the pair of virtual antennas, and the range information and the phase information.
