The design and implementation of underwater acoustic signals data acquisition and storage system based on FPGA is introduced in this paper. It describes the overall design, hardware design and software design of the system. The control and processing core of the data is FPGA, and NAND Flash is the storage medium whose storage capacity can reach 2GB. The system is consisted of data acquisition module, data slorage module and RS232 serial communication module. The system is reliable and stable, small, and has low consumption and large capacity. The experiment shows that the performance of the system can meet the design requirements.
