摘要
对近场声全息(NAH,near-field acoustic holography)技术的最新研究进展进行了综述。重点介绍了Patch技术、非稳态声场的重建、移动声源的分析和不相干声场分解等研究方向上取得的研究成果。对制约当前NAH技术发展的一些关键问题进行了分析,并对其发展前景提出了展望。
This paper gives a comprehensive description of new progress made in the research on near- field acoustic holography, with the focus on the introduction of the achievements which have been made in Patch technique, non-stationary sound field reconstruction, moving-source analysis, and par- tial sound field decomposition of non-coherent sound sources. Some key problems in the development of NAH technology are analyzed. Moreover, the prospects for its future development are presented.
