基于ADS5547的雷达中频信号数字下变频处理

Digital Down Convert of Radar Intermediate Frequency Signal Based on ADS5547

分析了T/R组件实时性能对有源相控阵雷达天线工作状态影响的关键作用,阐述了怎样准确实时获取雷达信号,并进行下变频处理是进行雷达信号分析处理的一个基本问题,对雷达中频信号数字下变频技术进行了研究,实现了基于ADS5547雷达中频信号数字下变频处理方案,具有一定的实用价值。

This paper analyzed that T/R module is solid function to have the source the key function for mutually controlling a radar antenna work status influence,elaborated that how accurate solid acquire radar signal.And carrying on digital down convert handle is a radar signal to analyze a processed basic problem, to radar intermediate frequency signal carry on digital down convert handle technique to carry on a re-search.According to ADS5547 radar intermediate frequency signal,it realizes digital down convert han-dle,thus it has definite practicality value.
