【摘要】 采用声全息技术开展有限水域中运动声源识别及其声场预测，对于研究水下航行器的声源特性和声辐射特性具有重要意义。然而，运动声源辐射声压的获取和有限水域界面效应的影响给声全息技术在有限水域中的应用带来了困难。本文考虑声源运动，采用线阵测量并基于移动框架技术来获取运动声源辐射的全息面声压数据；考虑有限水域界面效应的影响，在三种不同界面情况下，基于等效源法思想分别构建了三种全息反演模型。以有限水域中的圆柱壳体为对象开展了数值仿真，结果表明，三种反演方法相较于未考虑界面反射的自由场反演方法可以获得更好的声源识别和声场预测效果。在湖中开展了运动标准声源试验，试验结果表明，所建方法可以实现声源的有效定位和声场的精确预测。更多还原

【Abstract】 The use of acoustic holography technology for identifying moving sound sources and predicting their sound field in limited water areas is of great significance for studying the sound source and radiation characteristics of underwater vehicles. However, the acquisition of sound pressure radiated by moving sound sources and the influence of interface effects in limited water areas have brought difficulties to the application of acoustic holography technology in limited water areas. In view of this, the motion of the sound source was considered and the linear array measurement and moving frame technology were used to obtain holographic pressure radiated by moving sound sources. Considering the influence of interface effects in limited water areas, three holographic inversion models were constructed based on the equivalent source method in three different interface situations. Numerical simulations were conducted on cylindrical shells in limited water areas, and the results showed that the three inversion methods can achieve better sound source identification and sound field prediction results compared to the free field inversion method without considering interface reflection. A moving standard sound source experiment was conducted in a lake, and the experimental results showed that the proposed method can effectively locate the sound source and accurately predict the sound field.更多还原
