摘要
基于DDS的线性调频信号产生方法具有许多其他传统方法不可替代的优越性。针对线性调频连续波雷达信号的要求,对ADI公司推出的AD985x和AD995x为代表的DDS器件的相关性能特点进行了比较、分析,为工程应用提供了相应的选择参考。
DDS-based linearly frequency modulated continuously wave(LFMCW) generator has many advantages over other methods.This paper concentrates on the performance comparisons of ADI DDS.Taking the representative AD985x and AD995x as an example,the various linearly sweep characteristics of DDS are analyzed and compared,and some application reference to chooses DDS is also provided.
