To enable position information and relative speed information with regard to each of a plurality of positions to be acquired at a faster rate of updating.SOLUTION: An acoustic sensor device of the present invention comprises: an acoustic array for transmission that transmits contiguous signals by acoustic beams of a plurality of fan beams; an acoustic array for reception that receives the reflected waves of the plurality of acoustic beams transmitted by the acoustic array for transmission; a transmission control unit for controlling the acoustic array for transmission and causing the acoustic beams to be transmitted; and a reception processing unit for calculating the distance to a reflector that reflected the plurality of acoustic beams and the relative speed to the reflector on the basis of the reflected waves received by the acoustic array for reception. The acoustic sensor device is installable in an underwater cruising or a surface cruising vehicle.SELECTED DRAWING: Figure 1

    【課題】複数の位置それぞれについて位置情報および相対速度情報を、より速い更新レートで取得できるようにする。【解決手段】音響センサ装置が、複数のファンビームの音響ビームにて連続信号を送信する送信用音響アレイと、前記送信用音響アレイが送信した前記複数の音響ビームの反射波を受信する受信用音響アレイと、前記送信用音響アレイを制御して前記音響ビームを送信させる送信制御部と、前記複数の音響ビームを反射した反射体までの距離、および、前記反射体との相対速度を、前記受信用音響アレイが受信した反射波に基づいて算出する受信処理部と、を備え、水中航走体または水上航走体に設置可能とする。【選択図】図1
