基于矢量传感器的海洋声场观测潜标系统

以三维矢量传感器为核心，构建海洋矢量声场观测潜标系统。潜标由定深锚固定，工作于指定海深，可完成海洋矢量声场信息的观测与存储。矢量传感器输出的矢量声信号，经前置预处理后采样，并以文件分配表（FAT）32文件格式存储于潜标微型快擦写存储卡（CF）中；矢量传感器水下姿态由潜标中三维地磁姿态仪实时给出。潜标集成USB传输模块，回收后可通过USB串口完成数据上传PC机。海试结果表明：潜标系统可正确记录海洋矢量声场信息，且可稳定水下工作90d以上。

Submerged buoy system for ocean sound field measurement based on vector sensor

A submerged buoy system for ocean vector sound field measurement is designed with the three-dimensional vector sensor as a core. The submerged buoy is anchored in fixed place and depth in ocean which can be used in observing and recording the ocean vector sound field. The vector sound signals from vector sensor is pre-processed , sampled and recorded in the compact flash card with the FAT32 data format. The underwater gesture of submerged buoy is given by three-dimensional geomagnetism compass in real time. USB module of submerged buoy is used in transmitting data to PC after the submerged buoy system is got back. The sea trial results indicate the system can record the vector sound field information correctly and work for over 90 d continuously.
