摘　　要：构建了一个以三维低频矢量传感器为核心的海洋矢量声场观测用浮标与潜标系统平台。水下潜标系统对矢量传感器拾取的声场声压与质点振速共4路信号进行预处理,并进行采集、解算与自存储。矢量传感器的水下姿态由潜标中电磁姿态仪给出。潜标与水面浮标由通信电缆连接,控制信息与数据信息可双向传输。浮标体集成扩频通讯电台,主控制台站通过无线电台完成对浮标与潜标的远程控制。外海试验表明:系统无线电通信速率可达11Mbps,作用距离15km,可在海上持续稳定工作30天。整套浮标与潜标系统已在工程项目中得到实际应用。A buoy-submerged buoy system based on three-dimensional vector sensor is proposed to measure the ocean vector sound field.The pressure and all three particle velocity signals measured by the vector sensor are preprocessed,sampled,calculated and self-stored by submerged buoy subsystem.The underwater gesture of the vector sensor is measured by electric-magnetic compass integrated in the submerged buoy.The buoy and submerged buoy are connected by the bidirectional communication cable which can be used to transmit the command information and data.With the help of the radio integrated in the buoy,the buoy and submerged buoy can be remotely controlled by the headquarters.The China Sea trial results indicated：11Mbps data rate at the range of 15km is attainable for the system which can stably work for 30 days in the ocean.The whole system has been used in the practical projects.
