A vector-hydrophone is composed of two or three spatially co-located but orthogonally oriented velocity-hydrophones plus another optional co-located pressure hydrophone. This direction finding algorithm may resolve up to four monochromatic sources. Cramer-Rao bounds for arrival angle estimates for this scenario are also derived.
