To provide an acoustic guidance system aiming for higher observation accuracy of a target and improvement of meeting probability.SOLUTION: According to an embodiment, an acoustic guidance system comprises a guidance propulsion device, an active sonar device and a guidance control device. The guidance propulsion device is loaded in an underwater navigation body and guides the underwater navigation body toward an underwater target. The active sonar device obtains position information of the target using a sonar signal. The guidance control device executes arrival estimation computation on the basis of the position information. The guidance control device comprises a guidance computation part. The guidance computation part supplies the result of the arrival estimation computation to the guidance propulsion device before sending out of the underwater navigation body. The active sonar device comprises an acoustic guidance part. The acoustic guidance part supplies a guidance instruction to the guidance propulsion device by an acoustic communication signal different from the sonar signal after sending out of the underwater navigation body.SELECTED DRAWING: Figure 1 【課題】 目標の観測精度を高めて会合確率の向上を図った音響誘導システムを提供すること。【解決手段】 実施形態によれば、音響誘導システムは、誘導推進装置と、アクティブソーナー装置と、誘導統制装置とを具備する。誘導推進装置は、潜航体に搭載され、当該潜航体を水中の目標に向け誘導する。アクティブソーナー装置は、ソーナー信号を用いて目標の位置情報を取得する。誘導統制装置は、位置情報に基づいて到来予測計算を行う。誘導統制装置は、誘導計算部を備える。誘導計算部は、潜航体の発出前に、到来予測計算の結果を誘導推進装置に与える。アクティブソーナー装置は、音響誘導部を備える。音響誘導部は、潜航体の発出後に、ソーナー信号とは異なる音響通信信号により誘導推進装置に誘導指示を与える。【選択図】 図１
