To provide a Fresnel zone inspection method that can efficiently inspect whether an obstacle for wireless communication is in a Fresnel zone, and an obstacle detection system used for the method.SOLUTION: An obstacle detection system 1 includes: an obstacle detection device 2 that obtains positional information on a measurement object that can be an obstacle in a wireless communication section and converts it into a three-dimensional coordinate value; a Fresnel zone calculation device 3 that obtains a three-dimensional coordinate value of a Fresnel zone in the wireless communication section; an obstacle determination device 4 that determines whether the measurement object is an obstacle for wireless communication by comparing the three dimensional coordinate values of the measurement object and the Fresnel zone; and a control device 5 that controls operations of the obstacle detection device 2 and the obstacle determination device 4.SELECTED DRAWING: Figure 1

    【課題】無線通信に対する障害物がフレネルゾーンに存在するか否かを効率よく検査することが可能なフレネルゾーンの検査方法とそれに用いられる障害物検出システムを提供する。【解決手段】障害物検出システム1は、無線通信区間において障害物となり得る測定対象物の位置情報を取得して3次元座標値に変換する障害物検出装置2と、無線通信区間内のフレネルゾーンの3次元座標値を取得するフレネルゾーン演算装置3と、測定対象物とフレネルゾーンの3次元座標値を比較することにより上記測定対象物が無線通信に対する障害物であるか否かを判定する障害物判定装置4と、障害物検出装置2乃至障害物判定装置4の動作を制御する制御装置5を備えている。【選択図】図1
