Torpedo sonar comprising a plurality of acoustic transducers

摘要

For reducing the number of acoustic transducers required by a torpedo sonar for target searched the transducers are arranged in four particular zones at the curved contour of the torpedo bow forming a conformal sonar array. A circular first zone covers the vertex region of the torpedo bow and is surrounded by a ring-shaped second zone. Extending from said second zone on both sides of the torpedo are third lateral transition zones, which change over into fourth lateral zones of constant width ending at the great circle of said hemispherical or paraboloid-shaped torpedo head.
