PROBLEM TO BE SOLVED: To select an appropriate detection method in accordance with the weather.SOLUTION: The detector includes: a transmitting/receiving unit for transmitting a transmission wave as well as receiving, via a transmission member, a reception wave generated by reflecting the transmitted transmission wave on a target; an imaging unit for picking up the image of the target via the transmission member; a water droplet detection unit for detecting a water droplet adhering to the transmission member; a first detection unit for detecting the target on the basis of the detection result of the water droplet by the water droplet detection unit and the reception wave received by the transmitting/receiving unit; and a second detection unit for detecting the target on the basis of the detection result of the water droplet by the water droplet detection unit and the image picked up by the imaging unit.

    【課題】天候に応じて適切な検出方式を選択する。【解決手段】検出装置は、送信波を送信するとともに、送信した前記送信波がターゲットによって反射されて到来する受信波を、透過部材を介して受信する送受信部と、ターゲットの像を、透過部材を介して撮像する撮像部と、透過部材に付着する水滴を検出する水滴検出部と、水滴検出部による水滴の検出結果と送受信部が受信した受信波とに基づいてターゲットを検出する第1の検出部と、水滴検出部による水滴の検出結果と撮像部が撮像した画像とに基づいてターゲットを検出する第2の検出部と、を備える。【選択図】図1
