Abstract： In the process ocean noise measurement target localization，the hardware system's noise level directly affects the accuracy reliability detection results.Therefore，improving the signal-to-noise ratio the detection system is a crucial task in the detection process. This paper aims to design a high signal-tonoise ratio data acquisition storage system based on a 48-element cylindrical array，by combining analog digital circuits with other technical means，to improve the signal-to-noise ratio the detection system in tasks such as underwater noise measurement， weak target measurement， acoustic positioning. After esting， the system's equivalent noise pressure spectrum level is 40.5dB@1kHz. ， the overall noise level in the working bwidth is lower than the ocean environmental noise level O-level sea state under normal circumstances， showing excellent performance in the existing domestic underwater acoustic array receiving system. The modular design concept the entire system provides it with flexible scalability，making it possible to fer an effective technical solution for different applications such as ocean noise measurement underwater targetlocalization.
