To provide a biological information detection device capable of detecting blood pressure of an object person while inhibiting it from interfering with a behavior of the object person.SOLUTION: A biological information detection device 1 includes a reception antenna 13 for receiving a radio wave radiated from a transmission antenna 12 and transmitted through an occupant P who is an object person, and an information control unit 20. The information control unit 20 includes an input part 21 for acquiring a reception signal according to the radio wave received by the reception antenna 13 when the radio wave is radiated from the transmission antenna 12, and a processing part 24 for calculating biological information on the basis of the reception signal acquired by the input part 21. The processing part 24 extracts a signal component generated resulting from a movement of the heart H of the object person from the reception signal, and calculates blood pressure of the object person as the biological information on the basis of the signal component.SELECTED DRAWING: Figure 1
【課題】対象者の行動の妨げとなることを抑制しつつ、対象者の血圧を検出可能な生体情報検出装置を提供する。【解決手段】生体情報検出装置1は、送信アンテナ12から放射されて対象者である乗員Pを透過した電波を受信する受信アンテナ13と、情報制御部20とを備える。情報制御部20は、送信アンテナ12から電波が放射された際に、受信アンテナ13が受けた電波に応じた受信信号を取得する入力部21と、入力部21が取得した受信信号に基づいて、生体情報を算出する処理部24と、を有する。処理部24は、受信信号から対象者の心臓Hの動きに起因して生ずる信号成分を抽出し、当該信号成分に基づいて、対象者の血圧を生体情報として算出する。【選択図】図1
