摘要

针对传统三维声纳装置体积庞大、设备沉重

在水下难以灵活作业的问题

设计了水下便携式三维声纳实时成像系统。通过现场可编程门阵列（FPGA）控制多路信号同步采样

优化波束形成算法大幅提高声纳信号处理速度

同时采用基于低功耗的数字媒体处理器以并行处理方式实时完成三维建模和图像显示。实验结果表明:系统续航时间可达4 h

水下零重量

可在40 m范围内实现角度分辨率1.2°的三维成像

图像刷新率可达25帧/s。

Abstract

Aiming at problem of large size

heavy weight and can’t work flexibly underwater of traditional 3D sonar device

a design of portable 3D underwater sonar real-time imaging system is proposed. Control multiple path signal for synchronization sampling by FPGA

beamforming algorithm is optimized to improve processing speed of sonar signal

digital media processor based on low power consumption is used to achieve 3D modeling and image display by the way of parallel processing. Experimental result shows that the system can work for 4 h offline

and its weight underwater is zero

and is able to form 3D imaging with a resolution of 1. 2° within the range of 40 m

and the image refresh rate can reach up to 25 frames / s.
