doi:10.3969/j.issn.1000-1093.2012.08.006

Abstract

Abstract: 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.

Key words: acoustics, vector array, matched field, Bartlett processor, 3D location
