Abstract
A dual channel digital hydrophone was researched and designed.FPGA is used to col-lect digital and amplified hydrophone signal,32 bit microprocessor STM32F107 and network inter-face chip DP83848 is used to achieve Ethernet in-terface design,which has less hardware,is easy to implement and use,suitable for the current net-work transmission systems.Through experiment, system transmission rates by measured is up to 400Kb/s,satisfy requirement of the hydrophone and array of hydrophones.The digital hydrophone has strong signal processing,the extracted infor-mation is more accurate,reliable,and the hydro-phone signals can be communicated to electronic e-quipment on the surface of the water through a va-riety of real time bus,can also be used as stand alone test system which has information processing and preservation.关键词
