FIELD: hydro-acoustics, possible usage close to noise-producing cover of blister or body of watercraft. ^ SUBSTANCE: hydro-acoustic antenna is positioned along contours of watercraft body in non-wave interference zone, formed by body or blister, and is made in form of equidistant array, composed of electro-acoustic transformers, dimensions of which are small relatively to length of wave. Transformers are positioned one relatively to another at distance of half the length of bending wave in material of interference source cover, which is the body of watercraft or blister at upper frequency of working range of antenna. ^ EFFECT: increased resistance to interference. ^ 4 dwg |
