To provide a railroad crossing obstacle detection device which has a high performance to detect a rod-like luggage and the like while belonging to a flat sweep radar system.SOLUTION: A railroad crossing obstacle detection device 1020 which comprises first flat sweep measurement units 11-13 and 21-23 that flatly sweep aerial transmitting waves 12a and 22a, acquire first measurement data of reflection positions, are arranged in a neighborhood of a railroad crossing road 30 and flatly sweep above the railroad crossing road 30 and first determination units 14 and 24 that determine the presence of an obstacle based on the first measurement data, comprises furthermore second flat sweep measurement units 15-17 and 25-27 that flatly sweep aerial transmission waves 16a and 26a, acquire second measurement data of reflection positions, are installed in a neighborhood of an end of the railroad crossing road 30 and flatly sweep the end of the railroad crossing road 30 vertically and second determination units 18 and 28 that determine the presence of an obstacle based on the second measurement data.SELECTED DRAWING: Figure 1

    【課題】平面掃引レーダ方式を踏襲しつつも棒状荷物などの検知性能が高い踏切障害物検知装置を実現する。【解決手段】空中伝搬波12a,22aを平面掃引して反射位置の第1測定データを取得する第1平面掃引計測部11〜13,21〜23が踏切道30の近傍に設置されて踏切道30の上方を横に平面掃引するとともに、その第1測定データに基づいて第1判定部14,24が障害物の存否判定を行う踏切障害物検知装置1020において、空中伝搬波16a,26aを平面掃引して反射位置の第2測定データを取得する第2平面掃引計測部15〜17,25〜27が踏切道30の端部の近傍に設置されて踏切道30の端部を縦に平面掃引するとともに、その第2測定データに基づいて第2判定部18,28が障害物の存否判定を行うようにする。【選択図】 図1
