Who are the key players in U.S. Department of Defense (DoD) research efforts in long-range acoustic communications, and what are they doing?
The Defense Systems Information Analysis Center (DSIAC) was asked to identify key players in U.S. Department of Defense research efforts in long-range (500–1,000 m) acoustic messaging. DSIAC searched open-source documents and the Defense Technical Information Center’s repository for relevant information, which was compiled into a report and delivered to the inquirer. Key players were organized by government, academia, and industry, followed by a summary of the research being done by each organization. Acoustic hailing devices and laser-based acoustic messaging were among the most prominent technologies discussed.
