Acoustic Tomography with Navy Sonars

Abstract

The long-term goal of this contract is to determine if a wide variety of Navy sonars can be used to map the sound speed field by means of acoustical tomography for use in research and surveillance. The Sound Surveillance Systems (SOSUS) have traditionally been used for obtaining acoustical tomography data. The Navy has many more sonars than these, and their use should significantly enhance the accuracy and resolution of tomographic maps.
