To provide a biological information detection device capable of suppressing deterioration in biological information detection accuracy resulting from a movement in the surrounding of an 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 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 object person on the basis of the reception signal acquired by the input part 21. The processing part 24 specifies a signal component generated resulting from a movement in the surrounding of the object person as noise contained in the reception signal, and calculates biological information from the reception signal with the signal component removed.SELECTED DRAWING: Figure 1
【課題】対象者の周囲の動きに起因する生体情報の検出精度の低下を抑制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。処理部24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、対象者の生体情報を算出する処理部24と、を備える。処理部24は、対象者の周囲の動きに起因して生じる信号成分を受信信号に含まれるノイズとして特定し、当該信号成分を受信信号から除去したものから生体情報を算出する。【選択図】図1
