AI Technical Summary
Existing underwater target identification systems suffer from narrow bandwidth, low communication rate, and high error rate, and compromise the concealment of underwater targets, making them difficult to effectively identify and locate in complex deep-sea environments.
Design an underwater target acoustic echo control device. By setting protrusions and grooves of different heights on the main flywheel and laying acoustic materials of different types and thicknesses, multiple reflection structures are constructed. Information is transmitted using passive echo mode to avoid interference from active signal transmission.
It enriches the content of information transmission, reduces underwater navigation resistance, maintains the concealment of underwater targets, and improves communication efficiency and concealment.
