Abstract:This paper describes a sonar system based on a hyperbolic-paraboloidal transducer beamformer. The array matrix composed of square sectioned elements is conformal to a doubly ruled surface of a hyperbolic paraboloid. The lines of elements in the array follow the surface rulings and are electrically configured to form multiple perpendicular linear array pairs. A multi-channel transmitter drives the transducer to ensonify an approximately square field of view of about 45 by 45 degrees either sequentially line by … Show more
