Claims (2)
- 設定された監視領域内に電波を送信し、その反射波を受信する送受信器と、
前記電波を前記送受信器に向けて反射する反射板と、
前記監視領域内の背景パターン情報を記憶し、前記背景パターンの反射波を前記背景パターン情報により相殺し、前記監視領域内の障害物を検知する信号処理部と、を備え、
前記監視領域を前記反射板の内部に設定することで、反射板からの反射波を信号処理部の処理対象外とし、前記背景パターン情報には、前記反射板の情報は記憶されない、踏切障害物検知装置。 - 請求項1に記載された踏切障害物検知装置であって、前記信号処理部は、処理対象外である前記反射板からの反射波を検知対象とすることで、前記送受信器が故障状態であるか否かを判定する、踏切障害物検知装置。
