高速数据采集卡在雷达信号采集和分析中的应用

Application of High-speed Data Acquisition Card in Radar Signal Acquisition and Analysis

随着电子器件的高速发展和计算机总线技术日趋成熟 ,数据采集的采样速率已经得以飞速发展 ,现今的 A/D采样率已经达到 10 GS/s,通过 A/D采样在中频对雷达进行信号处理变得完全可能。本文介绍一种基于 PCI总线技术的数据采集卡 。

Data acquisition sampling is ever increasing fast with developments of electronic devices and computer bus technique. A/D sampling rate nowadays reaches 10GS/s,which makes it possible to sample the radar signals at intermediate frequency for further processing. This paper introduces a DAQ card based on PCI bus through which radar return signals are sampled and saved.
