Zusammenfassung:	To improve the accuracy of azimuth operation.SOLUTION: A radar device according to one embodiment has a reception unit, and a calculation unit. The reception unit has a plurality of reception antennae composed of antenna elements, and receives a reception wave with a known arrival direction. The calculation unit calculates a correction value that corrects an error component included in a reception signal, depending on a beam pattern of an antenna element on the basis of a reception signal of a reception wave received by the reception unit.SELECTED DRAWING: Figure 2 【課題】方位演算の精度を向上させること。【解決手段】実施形態に係るレーダ装置は、受信部と、算出部とを備える。受信部は、アンテナ素子で構成された複数の受信アンテナを有し、到来方向が既知の受信波を受信する。算出部は、受信部によって受信された受信波の受信信号に基づいてアンテナ素子のビームパターンに依存し、受信信号に含まれる誤差成分を補正する補正値を算出する。【選択図】図２
