To meet the critical need for compact, multifunctional acoustic vector sensors on deep-sea unmanned platforms such as acoustic profiling buoys and underwater gliders, we have developed a novel composite resonant acoustic vector sensor capable of large-depth operations. The sensor innovatively integrates the sound pressure channel and the vector channel, and utilizes the conjugate cross-spectrum between them to effectively redu...

Ocean Acoustic Tomography (OAT) is an efficient and economical marine acoustic observation technique. Targeted observation is an appealing procedure to reduce the uncertainty of ocean environment prediction through additional observation. This study aimed to assess the validity of OAT as an observation method for targeted observation. OAT based on Niche Genetic Algorithm was employed to extract sound speed and temperature prof...
