摘要
对新型数字图像声纳系统中的高速多通道数据采集与信号处理部分的硬件设计和工作原理进行了论述。简述了数字成像声纳的工作原理 ,并提出了与成像声纳工作方式相适应的数据采集、缓存、传输和处理方案。详细讨论了多通道并行数据采集、缓存的机制 ,以及利用光纤进行远距离高速数据传输的实现方法和基于TMS3 2 0 C670
The multi channel data acquisition and signal processing system in the novel digital imaging sonar are studied. The principle of the imaging sonar is described, and the corresponding scheme of data acquisition, storage, transmission and processing is introduced. The hardware design and implementation of multi channel data acquisition, storage, and optical fiber transmission system are discussed in detail. Furthermore, the hardware design and the scheme of the task distribution of the signal processing system are studied.
