The Joint SACLANTCEN/USA Towed Vertically Directive Source TVDS
Abstract
For some years SACLANTCEN has conducted environmental studies utilizing a low-frequency sound source. Operating at frequencies around 400 Hz and 960 Hz, a comprehensive data base has been built up which has been used by scientists at SACLANTCEN and national research centres to refine theoretical treatments of low frequency sound transmission, to validate work on forward and back scattering, and to investigate geological factors giving rise to discrete reflectors in an attempt to assess the potential of low frequency active sonar adjuncts. Though these studies have been extremely successful, by 1993 it was clear that the scope of the work was being currailed by limitations of the sound source. The acoustic power was too low for wide area reverberation research, the inability to transmit more than a single frequency at any one time and the limited transmit bandwidth were severely hampering several studies. The wide transmit beam width was also not well matched to the environment or the potential operational user, particularly in shallow water.
