摘要
介绍了AD9910的功能特点,论述了利用FPGA控制DDS模拟线性调频雷达信号的设计方案,并对该方案的仿真结果进行了分析。实验结果表明,基于该方案产生的雷达信号频谱纯净稳定,可以满足雷达系统的要求。
This paper firstly introduces the functions and characteristics of AD9910,then discusses a scheme using FPGA control DDS to simulate chirp signal,and finally makes a brief analysis of the simulation results of the scheme.Experimental results show that the frequency spectrum of the radar signal based on this scheme is clean and stable,so it can meet the requirements of radar systems.
