Research On Analog to Digital Convert Design of DRFM

数字射频存储器(DRFM)采用高速采样和数字存储作为其技术基础,具有对射频和微波信号的存储和再现能力,可实现对雷达设备性能的无线检测。但DRFM系统模拟前端一直是保证系统高速高精度信号采集与回放的设计难点。本文以实际工程项目为背景,着重论述了在本项目中解决DRFM系统模拟前端设计中诸多难题的方法。

Digital radial frequency memorizer （DRFM） with high-speed sampling and digital recording as its technical foundation has the ability to memorize and playback radial frequency and microwave signal, can actualize wireless detecting of capability of radar e- quipment. However, there are several difficulties in designation of high-speed high-precision data acquisition and playback.In the background of practical engineering project, Furthermore, the methods of difficulty solutions in analog part of DRFM system design are analyzed emphasizely in this paper.
