Abstract
There is provided a radar device configured to detect a target by executing signal processing on the basis of a transmission wave and a reflection wave of the transmission wave reflected on the target. An antenna unit having a plurality of antennas arranged in a vertical direction. A calculation unit configured to calculate vertical azimuths of the target on the basis of the reflection waves with respect to the transmission waves transmitted from each of the antennas, and to accumulate calculation results. An estimation unit configured to calculate moving average values of maximum values of the vertical azimuths on the basis of the calculation results accumulated by the calculation unit, and to estimate the moving average values of the maximum values, as a height of the target.
