Imaging of Artificial Bubble Distribution Using a Multi-Sonar Array System

Bubble clusters present in seawater can cause acoustic interference and signal distortion during marine exploration. However, this also be used as an masking technique, which has significant implications for military purposes. Therefore, characterizing the distribution of bubble water would allow development anti-detection technologies. In study, a sea experiment was performed using multi-sonar array system bubble-generating material developed by our research group to obtain signals from artificial cluster characterize its distribution. The acquired data were preprocessed, reverse-time migration (RTM) applied dataset. For effective RTM, envelope waveform decrease computation time memory requirements. RTM results could effectively image characteristics clusters. Compared with Doppler current profiler data, backscattering strength boundary imaged estimated range between −30 −20 dB. three-dimensional open determined through RTM. Furthermore, obtained study reference future studies.
