Directional Low-Frequency Ring Hydrophone.
Abstract
The patent application relates to directional low frequency ring hydrophones and more particularly to small size circumferentially polarized ring hydrophones operable at extremely low frequencies which are well below any axisymmetric mechanical resonances of the ring, such a ring hydrophone having a high sensitivity to sound incident in the axial direction compared with the sensitivity to sound incident in the radial direction over a band of very low frequencies.
