Problems solved by technology

However, high-precision clocks are expensive, and time errors are constantly accumulating, which will inevitably exceed the allowable range after long-term work
Surface antennas have disadvantages such as poor security and high power consumption, and are not suitable for deep sea environments; the limitations of energy and data have affected the performance of many important functions of existing underwater acoustic signal transmitting equipment

Abstract

The invention belongs to the technical field of marine acoustic instruments and equipment, and particularly relates to a cabled underwater acoustic launching subsurface buoy which comprises shore equipment, a submarine cable (6) and underwater equipment. The shore equipment and the underwater equipment are connected through the submarine cable (6); the submarine buoy has a high-power punctual transmitting function of various acoustic signals, can work continuously for a long time around the clock, overcomes the defect that an existing transmitting submarine buoy is limited by severe weather and energy supply, can provide powerful support for marine acoustic technology research, and has very important significance in developing research on underwater acoustic physics, communication navigation, marine environment and the like.

Description

technical field [0001] The invention belongs to the technical field of marine acoustic instruments and equipment, and in particular relates to a cabled underwater acoustic launching submersible and a method thereof. Background technique [0002] The underwater acoustic launch submersible is an underwater acoustic experimental device that is placed in the sea and can actively emit acoustic signals, providing an acoustic signal source for underwater acoustic physics research. Generally speaking, acoustic emission submersibles mainly include: signal generation equipment, power amplification equipment, acoustic emission transducers and power supply equipment; they can be installed on different platforms to realize the acoustic signal emission function, and through cooperation with the acoustic receiving device, complete Search, identification, tracking and underwater acoustic communication for underwater targets. [0003] There are two main types of underwater acoustic launchin...
