Abstract :

A vector hydrophone is composed of two or three spatially collocated but orthogonally oriented velocity hydrophones plus an optional collocated pressure hydrophone. A vector hydrophone may form azimuth-elevation beams that are invariant with respect to the sources’ frequencies, bandwidths and radial locations. This paper characterizes the minimum variance distortionless response (MVDR) beam patterns associated with a single underwater acoustic vector hydrophone located near a reflecting boundary for the far-field underwater acoustic sources.
