Abstract
A system of sonar platforms designed for use in moderate depth water is disclosed, with each platform having a plurality of transducer modules mounted thereon. Each transducer module has a plurality of sonar transducers mounted in columns. The transducers are electronically grouped in two groups for sensing of reflected signals, to provide a means of bearing calculation by the phase monopulse method. The transducer modules are identical and interchangeable, so that any module can be mounted in any position on any platform. Each platform is hexagonal, with up to six transducer modules mountable on each platform to provide the desired pattern of sonar coverage for the platform. The platforms can be arranged in any desired pattern to provide the desired sonar coverage of a particular body of water.
