摘要
提出一种基于数字信道化接收的数字射频存储(DRFM)系统设计方法.介绍了数字信道化接收原理及其工程实现结构,在传统DRFM系统基础上提出一种新的DRFM系统实现结构,给出了雷达干扰系统实例说明.基于数字信道化接收的DRFM系统可实现大的频率覆盖范围,且保证信号恢复精度,可实现复杂欺骗信息调制.
A new digital radio frequency memory(DRFM) system architecture based on digital channelized receiver is introduced.The theory of channelized receiver is stated and the realization structure based on polyphase filters is derived,and the diagram of radar countermeasure system based on this idea is proposed.The DRFM system based on digital channelized receiver take the advantage of broadband coverage of channelized receiver,and guarantees the frequency accuracy of the reproductive signals.The system can significantly reduce the requirement for calculation resources,the complex modulation process can easliy be achieved due to the decimated low speed data rate.
