PROBLEM TO BE SOLVED: To provide an object detector capable of accurately calculating positions of a plurality of objects.SOLUTION: An object detector 20 comprises: first acquisition means acquiring a plurality of reflection waves received at a first position as a first direct wave group and acquiring a plurality of reflection waves received at a second position as a first indirect wave group when transmitting a first survey wave; second acquisition means acquiring a plurality of reflection waves received at the first position as a second indirect wave group and acquiring a plurality of reflection waves received at the second position as a second direct wave group when transmitting a second survey wave; and determination means determining whether an object is actually present by comparing detection distances calculated on the basis of reception time of each reflection wave in each direct wave group or each indirect wave group.SELECTED DRAWING: Figure 1

    【課題】複数の物体の位置を適正に算出することが可能な物体検知装置を提供する。【解決手段】物体検知装置20であって、第1探査波の送信に際して、第1位置で受信した複数の反射波を第1直接波群として取得するとともに、第2位置で受信した複数の反射波を第1間接波群として取得する第1取得手段と、第2探査波の送信に際して、第1位置で受信した複数の反射波を第2間接波群として取得するとともに、第2位置で受信した複数の反射波を第2直接波群として取得する第2取得手段と、各直接波群又は各間接波群における各反射波の受信時刻に基づき算出された検知距離を相互に比較して物体が実在するか否かを判定する手段と、を備える。【選択図】 図1
