Vector Hydrophone Array: Measurement of Bearing

BII7060 series vector hydrophone arrays include two perpendicular line arrays, planar, and 3D discrete arrays which consist of Pressure Gradient Hydrophones or Dipole Hydrophones: Quadrupole Hydrophone Array and Tetrahedron Array. They are sensitive to both the amplitude and the direction of the acoustic wave in a plane, provide cosine and sine (or orthogonal "figure 8") directivity patterns in dipole plane. Depending on complex weighting of each element, different directional beam patterns can be implemented such as cardioid and endfire. 4-element Tetrahedron Array consist of four sensing elements with four outputs of each elements in a small compact size for estimation of bearing (azimuth) and elevation of sound source. 5-element planar array consist of five sensing elements with five outputs of each elements for estimation of bearing (azimuth) and elevation of sound source. Two perpendicular line arrays (each line array has 21 elements) with Mills Cross implement beam steering to track and locate sound sources, and measure their bearing angles.
