摘要
水下目标辐射噪声采集和处理系统是一套高速多通道采集和处理系统，其主要的任务就是将水下目标辐射噪声信号采样存盘。
本论文对高速多通道采集和处理系统的设计和实现进行了研究，论文的主要研究工作包括：设计一套模拟噪声源；根据水下目标辐射噪声的检测和识别要求进行了高速多通道采集和处理系统的设计和实现研究；完成了相应的PCI、USB Windows2000驱动程序的开发；使用VC++6.0编写了采集控制和波形显示界面。
论文着重讨论了硬件接口和软件接口的设计问题。硬件接口的设计主要考虑高速和数据传输的稳定性，软件接口主要讨论如何配合硬件工作，以达到最优化工作效率。
系统在松花湖进行了湖试，进行了实际的检验，证明了该系统能连续可靠的工作。
The data acquisition and processing system of underwater target radiate-noise is a high-speed multi-channel data acquisition and processing system.Its main task is to sample the underwater target radiate-noise signal and store the data to the disk.
This thesis researches the design and implementation of underwater high-speed multi-channel data acquisition and processing system.There are some contents to be presented including designing a set of noise signal generator;design and implementation of underwater nosie high-speed multi-channel data acquisition and processing system;programming the Windows 2000 device driver cl PCI and USB with DDK2000;programming user interface of the control of the acquisition and display of the image with VC++6.0 .
This thesis aims at hardware and software design of the system.During the hardware design,I think mostly over high-speed and stability of data transfering.and for the software design,I consider how to cooperate with the hardware design.
The whole system has been verified in experiment on the Song Hua lake in September this year.
