PROBLEM TO BE SOLVED: To provide an underwater acoustic communication system that expands a range in which underwater acoustic communication is possible between a ship or the like in the vicinity of a water surface and an underwater vehicle under water.SOLUTION: The underwater acoustic communication system, in which communication is performed by using an acoustic signal between floating acoustic communication means 30 disposed in the vicinity of a water surface A and a sailing body acoustic communication means 40 provided in an underwater vehicle 22 traveling in the water, includes acoustic communication relay means 50 disposed in a predetermined region X below the water surface A. At least when the underwater vehicle 22 travels beyond the predetermined region X, the floating acoustic communication means 30 and the sailing body acoustic communication means 40 perform acoustic communication via the acoustic communication relay means 50.SELECTED DRAWING: Figure 1

    【課題】水面近傍にある船舶等と水中にある水中航走体との水中音響通信可能範囲を拡大する水中音響通信システムを提供すること。【解決手段】水面Aの近傍に配置した浮体音響通信手段30と、水の中を航走する水中航走体22に設けた航走体音響通信手段40との間で音響信号を利用して通信を行う水中音響通信システムにおいて、水面Aから下方の所定領域Xに配置した音響通信中継手段50を備え、少なくとも水中航走体22が所定領域Xを超えて航走するときに音響通信中継手段50を介して浮体音響通信手段30と航走体音響通信手段40が音響通信を行う。【選択図】図1
