PROBLEM TO BE SOLVED: To provide a device for estimating the position of an object even in the case that a signal which can estimate the position of the object can be observed only intermittently in time.SOLUTION: A detection system for a ship is a detection system including a detection part for detecting vibrations from an object existing underwater to acquire vibration information, a determination part for determining a state of a ship, and an estimation part for acquiring information of the object by using vibration information at timing when the determination part determines that a state of the ship can estimate information of the object on the basis of the vibration information.SELECTED DRAWING: Figure 2 【課題】物体の位置を推定できる信号が時間断続的にしか観測できない場合であっても、物体の位置を推定する装置を提供する。【解決手段】船舶用の検知システムであって、水中にある対象物からの振動を検知して、振動情報を得る検知部と、船舶の状態を判定する判定部と、判定部により船舶の状態が、振動情報に基づいて対象物の情報を推定可能と判定されたタイミングの振動情報を用いて、対象物の情報を得る推定部と、を有する検知システムである。【選択図】図2
