Abstract : A program of research in underwater acoustics has been in operation at Catholic University for seven years. This is a report for work accomplished in the time period July, 1969, to October, 1970. Twelve articles have been published or accepted for publication, nine papers have been presented at meetings, sixteen articles have been submitted for publication and two reports have been issued. In addition, the program has sponsored the completion of eight doctoral and three masters dissertations. Eleven doctoral and two masters dissertations are in progress. Significant research results are thought to be in acoustic radiation from multiple surfaces, acoustic signature of an imploded submerged body, experimental determination of mutual impedance using face velocity measurements, a monopulse tracking technique for linear arrays, scattering work, sound propagation in wedge shaped shallow water, propagation in a random media and sound radiated by a moving rigid surface.
