Abstract : An acoustic parametric beam transmission and receiver system was designed using a USRD type E-8 transducer as a parametric source. An LC-32 was used as the receiving hydrophones. The study has been divided into four sections. The first section deals with the design and evaluation of the optimum parameters of this acoustic parametric system. The second section deals with the surface reflection of the parametric beam from a water-air surface. The third section deals with the shipboard use of this acoustic parametric system. The fourth section deals with the summary of the study carried out in the first three sections.
