Abstract
Sonar systems and related methods are provided. A sonar system includes a transducer array having a transverse axis and a longitudinal axis disposed perpendicularly thereto. A processor is operative to associate signals with a plurality of transducers in the transducer array so as to form a first acoustic beam, which propagates in a beam first direction and has a first beam width in a first transverse plane. The first transverse plane extends along the beam first direction and contains the transverse axis of the transducer array. A beam spreading device having a curved surface is positioned relative to the transducer array such that the first acoustic beam impinges on the curved surface. Following impingement on the curved surface, the first acoustic beam propagates in a beam second direction and has a second beam width in a second transverse plane. The second beam width is greater than the first beam width.
