The invention aims to provide a ship structure acoustic radiation characteristic intelligent active control method which is used for detecting ship vibration noise, pressure, temperature, and the likeacoustic and environmental information using perception sensors, extracting required ship radiation noise signals and acoustic situation information through an acoustic analysis and feature extraction module, generating signals with specific frequency and amplitude by using a self-adaptive control algorithm according to the ship radiation noise signals and the acoustic situation information usinga controller, and finally controlling the acoustic radiation characteristics of the ship structure through a driving module and an active actuator. According to the method, ship voiceprint characteristics can be changed, acoustic false indication camouflage for spoofing and puzzling the opposite side can be realized, and ship radiation noise reduction, acoustic characteristic signal reduction, hiding and intelligent sound stealth can be realized when necessary, so that the ship intelligent active control and sound stealth performance can be effectively improved.
本发明的目的在于提供船舶结构声辐射特征智能主动控制方法,感知传感器探测船舶振动噪声、压力、温度等声学和环境信息,经声学分析与特征提取模块提取所需的船舶辐射噪声信号和声学态势信息,控制器根据船舶辐射噪声信号和声学态势信息,利用自适应控制算法,产生特定频率和幅值的信号,最后经由驱动模块、主动作动器实现对船舶结构声辐射特征的控制。本发明既可以改变船舶声纹特征,实现欺骗和迷惑对方的声学示假伪装,又可在必要时,实现主动抑制消减船舶辐射噪声,消减自身声学特征信号,“隐藏”自己,实现智能声隐身,以此有效提高船舶智能主动控制和声隐身性能。
