Comparative Beamforming and Acoustic Inversion Studies Employing Acoustic Vector Data in Shallow Water

Abstract

The goals of this research included comparisons of standard and novel, non-standard processing techniques on linear arrays of vector sensors, and development of new inversion methods based on information contained in the acoustic vector field. A result of this study is then to show how the additional information contained in the acoustic vector field (pressure and particle velocity) may be used to improve the results of inversion schemes and provide more robust estimates of source direction from array beamforming.
