- Towed array plane and non-planewave beamforming under ship's maneuveringPublication . Felisberto, P.; Jesus, S. M.Towed hydrophone arrays are commonly used for determining the spatial characteristics of the underwater acoustic field. The assumptiont that the hydrophones lie in a straight and horizontal line is often made when beamforming the hydrophones outputs.
- Towed array geometry estimation during ship's moneuveringPublication . Jesus, S. M.; Felisberto, P.; Coelho, F.Towed arrays of hydrophones are commonly used as receiver apparatus for determining the directionality of the underwater acoustic field. It is well known that a line array beam response has a inherent left-right ambiguity and that any deformation of the array will produce a distortion on the estimated acoustic field directionality.
