Underwater high-speed target track measurement system

The invention aims at providing an underwater high-speed target track measurement system which comprises a water surface location unit, a synchronizer and an acoustic beacon that are sequentially connected, wherein the water surface location unit comprises an underwater transducer base matrix, a signal preprocessing system, a digital signal processing unit an d a computer which are sequentially connected; the synchronizer comprises a logic control module and a synchronization signal generation module which are connected; and the acoustic beacon comprises an emission control module, an emission power amplification module and an emission transducer which are sequentially connected. The underwater high-speed target track measurement system has high-precision location capability, is used for accurately detecting an underwater movement track of a target, has complete track measurement of the high-speed movement target, and has the advantages of simple structure, convenience for installation and operation as well as use. The underwater high-speed target track measurement system can be used for observing the movement condition of the underwater operation target, and can especially realize the track measurement of the high-speed movement target for research and analysis and use of a user.
