中文摘要：
针对水下结构体辐射声场的测试及分析问题,提出一种基于近场声全息的辐射声场可视化方法,采用平面近场声全息技术完成声场测量,给出声压数据场的获取方法,并运用光线投射算法对单频点上声压场进行体绘制,较好地呈现了某频点上辐射声场的声源位置、强度分布及衰减情况.
英文摘要：
Aiming at the measurement and the analysis of the radiated acoustic field of the underwater structure, a new method was put forward for visualizing underwater radiated acoustic field based on the near-field acoustical holography （NAH）. It can measure the radiated acoustic field by NAH technology and show how to acquire the sound pressure data field. It uses the ray-cast- ing algorithm to complete the volume rendering of the sound pressure data field on certain frequency, which presents commendably the location of the sound source, the distributing of the sound power and the status of the attenuation on certain frequency.
