PROBLEM TO BE SOLVED: To provide a technique for achieving the size reduction of a radar device.SOLUTION: An antenna comprises: a first transmission antenna outputting a transmission wave in an upper right direction of a road surface; a second transmission antenna outputting a transmission wave in an upper left direction of the road surface; a third transmission antenna outputting a transmission wave in a lower right direction of the road surface; and a fourth transmission antenna outputting a transmission wave in a lower left direction of the road surface. The transmission waves output from the first, second, third, and fourth transmission antennas partially overlap transmission ranges of the transmission waves output from the adjacent transmission antennas, respectively. With this configuration, the antenna can contain targets different in position in a perpendicular direction to the road surface by using the two types of transmission antennas each for upper and lower directions without the need to provide transmission antennas for a horizontal direction.

    【課題】レーダ装置を小型化する技術を提供する。【解決手段】路面に対し右上方向に送信波を出力する第1送信アンテナと、路面に対し左上方向に送信波を出力する第2送信アンテナと、路面に対し右下方向に送信波を出力する第3送信アンテナと、路面に対し左下方向に送信波を出力する第4送信アンテナとを備え、第1、第2、第3、および、第4の複数の送信アンテナのそれぞれから出力される送信波は、隣接する送信アンテナから出力される送信波の送信範囲と一部が重複する。これによりアンテナは、水平用の送信アンテナを設けることなく、上方用および下方用の2種類の送信アンテナで路面に対し垂直方向に位置の異なる物標を送信範囲に含めることができる。【選択図】図4
