Receiver System Design Of Vector Sensor Array

Vector sensor array is a hotspot technique in the field of underwater acoustic torpedo and underwater torpedo. This dissertation aims at the design of receiver system of vector sensor array. This system is a data collection device correspond with vector sensor array, its main task is the information acquisition and storage. In order to verify vector algorithm using the data collected, we need a receiver system of vector sensor array to gather pure underwater acoustic.In terms of the system's task and requirement, an experimental resolving project is put forward, which includes a buoy system and a station system. The experiment equipment has 24 gathering data channels and can sample the signals from six transducers simultaneously. Every channel can be controlled by optical fiber in distance, through which can alter the plus and filter band of the receiver.The buoy system consists of signal conditional circuit, sample control board, data storage board and power supply board. Because the buoy system is powered by battery, its power dissipation is a serious problem and every module have been tried to reduce power dissipation in the paper. Digital Signal Processor (DSP) and Field Program Gate Array (FPGA) have been used in the circuit, which made the hardware smaller, decreased the power consumption and enhanced the system reliability.The station system comprises signal receiver board and monitor program, its task is to storage data, control status and send instruction.The device has been debugged successfully and its main performances have been provided in the appendix.
