Geometric Phased Beam Diver Held Sonar

Abstract

A design for an underwater acoustic imaging system that would he portable enough to be operated by a diver was developed utilizing the geometric phased beam or 'doily' array concept. The 'doily' array design provides multiple beamsteering capability while drastically reducing the number of elements required. The system would operate in the I to 6MHz frequency range and only require 1808 channels. This report documents the state of the design at the end of the program.
