Hardware Design Of Vector Hydrophone Array Signal Processing Platform

From the beginning of this century, in order to give full play to the submarine in the future sea battle killer role. Navies to leave no stone unturned to improve submarine acoustic stealth performance. Because of this.underwater target detection system put forward higher requirements, the signal processing platform is the most importent part of underwater target detection system.mainly to complete the underwater acoustic signal conditioning, conditioning signal collection,storage, transmission and real-time processing and other work.The paper based on a vector hydrophone line array sonar system. mainly to complete the sigynal and information processing platform hardware design and debugging, and complete the system of data acquisition, storage, transmission and the corresponding software design. Hardware platform design includes chip selection, circuit schematic design and PCB design, the mian control chip selected Xilinx ZYNQ fpga.the signal processing part selected the DSP6678 as the core processing chip. The software design mainly includes two parts: FPGA and ARM. the FPGA chip mainly include Verilog program writing, timing constraints and the I / O tube the physical constraints of the foot, of multiple signals of vector and scalar is collected, packaged, cache, and other work: ARM part mainly includes the Linux operating system structures, character device driver programming and Linux under the C language program of preparation, completed in Linux operating system under the original data storage and network data distribution and other work.Evventually, by laboratory debugging,testified the system's data acquisition, the original data storage. data network transmission functions can satisfy the needs of system design, the twice test on the lake test to verify the stability of the system is verified. then points out the system actual with existing defects, and puts forward some possible solutions for improvement.
