| الوصف: | Ship wakes, which are inevitably caused by ship movement, are a subject of great interest for military purposes. In this study, we created an underwater acoustic signal measuring device to characterize the distribution of wakes from a ship maneuvering in a real ocean environment. Two sets of multi-array sonar systems consisting of multiple projectors and multiple hydrophones were fabricated to acquire underwater acoustic signals. The systems were then placed vertically at a certain distance from each other in the sea. Afterward, we stably acquired the transmitted and scattered signals from the bubble wake generated by an actual ship. The distribution of bubbles in the ship's wake was then imaged by applying the RTM (reverse-time migration) and WI (waveform inversion) numerical analysis techniques to image the bubble distribution in the ship wake. Finally, the results obtained using the two aforementioned techniques were analyzed and compared. |
