PROBLEM TO BE SOLVED: To accurately set a plurality of detection object areas in an area that includes a pedestrian crossing.SOLUTION: A radio wave sensor of the present invention comprises: a transmission unit for transmitting a radio wave to a target area that includes a pedestrian crossing; a reception unit for receiving a radio wave; a calculation unit for calculating the direction in the target area from the radio wave sensor to a reference object and the distance between the radio wave sensor and the reference object on the basis of the radio wave received by the reception unit; and a setup unit for setting a plurality of sub-areas in the target area on the basis of the direction and distance calculated by the calculation unit. The calculation unit further calculates, on the basis of the radio wave received by the reception unit, a detection direction from the radio wave sensor to the object in the target area, and a detection distance between the radio wave sensor and the object. The radio wave sensor further includes a detection unit for detecting the object for each sub-area on the basis of the detection direction and the detection distance.SELECTED DRAWING: Figure 3

    【課題】横断歩道を含むエリアにおいて、複数の検出対象エリアをより正確に設定する。【解決手段】電波センサは、横断歩道を含む対象エリアへ電波を送信する送信部と、電波を受信する受信部と、前記受信部によって受信された電波に基づいて、前記電波センサから前記対象エリアにおける参照物体への方向、および前記電波センサと前記参照物体との間の距離を算出する算出部と、前記算出部によって算出された前記方向および前記距離に基づいて、前記対象エリアにおける複数のサブエリアを設定する設定部とを備え、前記算出部は、さらに、前記受信部によって受信された電波に基づいて、前記電波センサから前記対象エリアにおける前記対象物への検出方向、および前記電波センサと前記対象物との間の検出距離を算出し、前記電波センサは、さらに、前記検出方向および前記検出距離に基づいて、前記サブエリアごとに前記対象物を検知する検知部を備える。【選択図】図3
