Abstract

For reducing the number of acoustic transducers required by a torpedo sonar for target searching, the transducers are arranged in four particular zones at the curved contour of the torpedo bow forming a conformal sonar array. The circular first zone covers the vertex region of the torpedo bow and is surrounded by a ring-shaped second zone. Extending from the 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 the hemispherical or paraboloid-shaped torpedo head.
