Wireless Communication Based Sonobuoy Signal Acquisition System Design

This paper describes the design of a hydroacoustic signal acquisition system for a sonobuoy platform. The system uses an FPGA for signal processing and is capable of acquiring and transmitting hydroacoustic signals in the frequency range of 20 Hz to 20 kHz, even in the presence of complex noise. It is equipped with a wireless transmission module (A69-T2G4A20D1a) for data communication and also includes a mainframe computer for displaying the acquired signals. Experimental tests confirmed that the system meets the design requirements and is valuable for acoustic buoy signal acquisition and wireless communication.
