摘要
文中基于软件无线电技术,针对雷达的接收机中频进行了数字化设计,结合实际,对实现数字接收的硬件方案进行了阐述,介绍了基于CPCI总线平台的A/D、D/A数字技术的工程实现方法,讨论了工程实践中的一些关键技术与技术要点。
Based on technologies of Software Radio, digital design is made in radar＇s IF receiver. Connected with practice, the hardware is described in which the digital receiving is realized in this paper. At the same time it is introduced about the engineering measures of A/D and D/A digital technologies based on CPCI bus. Also it is discussed about some key technologies and some technical points in engineering.
