基于参量阵的水下宽带波束合成系统设计与实现

摘要

For the improvement of the audio directional system, a set of beamforming system is designed, and proposed the basic principle, control plan,software and hardware design. In this system, is Xilinx a central control chip, with the parametric acoustic array and ultrasonic phased algorithm combined together as control strategies XC3S1400A. The experimental results show the system can control the direction of beam deflection. It can be used to complete beamforming.%针对现有声频定向系统进行改进,设计了一套波束合成系统.同时阐明了系统基本原理、控制方案、软硬件设计等问题.该系统以Xilinx公司FPGA芯片XC3S1400A为主控制芯片,以参量阵理论以及超声相控阵算法相结合作为控制策略.实验结果表明,该控制系统能够很好地控制声束的偏转方向,可用以完成波束合成的功能.
