AI Technical Summary

Problems solved by technology

The acoustics of the marine environment is complex, and the noise of the marine environment is the sum of non-correlated anisotropic and isotropic energy density fields. The current conventional technology is to measure the overall scattering characteristics of the wake through an external acoustic sensor. This method cannot obtain the internal acoustic characteristics of the wake, and each This kind of measurement is based on the scalar sound pressure receiver, i.e. hydrophone, and cannot completely observe all acoustic phenomena, such as the cancellation phenomenon of opposite energy flow intensity, etc. The foundation is more promising

The pedestal receiving device is only suitable for measuring the acoustic characteristics near the coast. The laying of multi-channel combined hydrophones in layers of ordinary submersible markers requires a test ship to cooperate with receiving information and energy supply, which is costly and limited to obtain continuous data.
