摘要
为研究MEMS矢量水听器在潜标中的应用,设计了一种可搭载其矢量阵列的潜标系统。系统阵列由4个矢量水听器组成,其姿态信息通过三维姿态传感器实时给出。矢量水听器的输出信号经前置放大电路预处理后传输至数据记录器,经采样后和姿态信息一起存储在Flash Memory中。对系统进行了海上试验,试验结果表明:潜标系统在水下工作稳定,可正确记录海洋中的水声信号。
A submerged buoy system is designed to study the MEMS vector hydrophone array＇ s application in it. The array consists of four vector hydrophones,its real-time gesture information is provided by three-dimensional attitude sensor. After a preamplifier circuit pre-processing, the output signals from vector hydrophone are transmitted to the data recorder which samples the signals and records them with gesture information in the flash memory. The sea trial results indicate that the system can work stably and record acoustic signals correctly.
