Abstract
A swath beam acoustic transducer (100) for projecting and/or receiving acoustic swath beams (108). The transducer comprises an array of active acoustic elements (104) that are arranged to collectively provide an elongate concave radiation surface (106) with an associated acoustic aperture (110). The array of active acoustic elements (104) is operable to project and/or receive acoustic swath beams (108) via the radiation surface (106).
