PROBLEM TO BE SOLVED: To reduce the load of arithmetic processing.SOLUTION: A rader device has the following scan modes: a first scan mode that scans a transmission wave in a horizontal direction with respect to each of multiple irradiation angles when an object to be monitored is detected at the multiple irradiation angles in a vertical direction; and a second scan mode that selects at least one of the irradiation angles when the object to be monitored is detected at the irradiation angles in the vertical direction, to scan the transmission wave in a horizontal direction with respect to the selected irradiation angle. A scan mode setting section of a lader device 1 sets the first scan mode or the second scan mode, on the basis of a relationship in distance between a vehicle and the object to be monitored.

    【課題】演算処理の負荷を軽減すること。【解決手段】走査モードとして、垂直方向における複数の照射角度で監視対象となる物体が検出された場合に、複数の照射角度のそれぞれに対して送信波を水平方向に走査する第1走査モードと、垂直方向における複数の照射角度で監視対象となる物体が検出された場合に、複数の照射角度の中から少なくとも1つの照射角度を選択し、選択された照射角度に対して送信波を水平方向に走査する第2走査モードと、を備え、レーダ装置1の走査モード設定部は、自車両と監視対象となる物体との間の距離などの関係性に基づいて第1走査モード又は第2走査モードを設定すること。【選択図】図1
