摘要
针对多路频分测控信号,提出了一种射频数字化信号处理的实现方法;并从工程实现的角度,讨论了高速ADC设计、多相变频和宽带调制等关键技术;最后,讨论了应用射频数字化方案后测控系统方案的组成。
In this paper, a RF-Digitalization signal processing scheme is proposed according the character- istics of frequency division multiplexing TT＆c signals. And three key problems, including the design of high speed ADC, polyphase digital down conversion, wideband modulator, are explained and analyzed from the aspects of implementation. At last, the architecture of TF＆C system based on the proposed RF- Digitalization scheme is discussed.
