Abstract
A synthesizer and method for the generation of underwater background acoustic signals employs digital signal generation and processing in a multiplexed format. The synthesized digital signals comprise components of shaped noise, simple sinusoids, or double-sideband, suppressed-carrier, modulated sinusoids, or a combination of one or more of these signal types. Among the acoustic signals which are digitally synthesized are acoustic signals generated by antisubmarine-warfare hardware such as sonobuoys and hydrophones.
