基于匹配场原理的矢量阵三维声源定位研究

摘要

将匹配场原理应用到矢量水平阵、矢量垂直阵上通过对声源穷举搜索实现三维定位,研究了声压、振速不同组合的定位性能,并对性能表现进行分析,最后给出了垂直阵、水平阵下性能相对好的组合方法.在垂直阵下,需要应用声压、余弦方向水平振速、正弦方向水平振速组合或者垂直振速、余弦方向水平振速、正弦方向水平振速组合;在水平阵下,需要应用垂直振速、余弦方向水平振速、正弦方向水平振速组合.%The matched field processing approach was applied to horizontal and vertical vector arrays for 3D source location by using exhaustive search. The influence of pressure and particle velocity on the location performence was discussed and analyzed. The parameters leading to better performance were given for horizontal and vertical arrays respectively. For vertical array, the combination of acoustic pressure, cosinusoidal horizontal velocity and sinusoidal horizontal velocity or vertical velocity, sinusoidal horizontal velocity and cosinusiodal horizontal velocity was needed for 3D location, while for horizontal array, the combination of vertical velocity, cosinusoidal horizontal velocity and sinusoidal horizontal velocity is needed.
