Abstract
A radar device includes: a receive antenna having a plurality of element antennas disposed in the left-right direction such that at least some of the plurality of element antennas is shifted in the up-down direction from the others; and a position detecting ECU. The position detecting ECU Includes: a first position detecting section, which detects a position of an object in the up-down direction, based on a phase difference between the respective reception signals received by the plurality of element antennas; and a first position correcting section which corrects the position in the up-down direction, based on the history of the position in the up-down direction, and obtains a first corrected position which is a position in the up-down direction after the correction.
