Thirty years of underwater acoustic signal processing in China
Abstract
The advances of new technology and theoretical development in 30 years of underwater acoustic signal processing and its applications in sonar design are presented in this paper. The topics include the research work in the field of underwater acoustic signal modeling, acoustic field matching, ocean waveguide and internal wave, the exaction and processing technique of acoustic vector signal information, space/time correlation characteristics of low frequency acoustic channel, the invariant feature of underwater target radiated noise, the transmission technology of underwater voice/image data, and its anti-interference technique. Some frontier technologies in sonar design are also discussed, including large aperture towed line array sonar, high resolution synthetic aperture sonar, deep sea siren and deep sea manned subsea vehicle, diver detection sonar and demonstration projector of national ocean monitoring system in China, etc.
