The transducers 18 and/or transducer arrays can be fitted to the hull of the vessel 2 such that the compass of the antenna 14, depending on the dimensions of the vessel 2, extends from the stem region of the vessel 2 along the side of the vessel 2 as far as the bow, around the bow, and 10 along the other side of the vessel 2 as far as the stern region. The invention furthermore concerns a submarine 2, on which an inventive underwater antenna 2 of this kind is fitted, and also a method for establishing the bearing, location and/or classification of a sound radiating target by means of an inventive underwater 15 antenna 2 of this kind.
