摘要
本文介绍了一个线性调频信号数字产生系统的设计与实现。首先对线性调频信号的两种主要数字产生方法进行了简要阐述和比较,然后根据直接数字合成(DDS)方法提出了线性调频信号产生方案,对其进行了系统实现研究,并给出了部分测试结果。
The article introduced design and implementation of a digilal generation system of linear frequency modulated signal. At first the article concisely described and compared two main digital methods of generating chirp signal, then proffered a scheme of generating linear frequency modulated signal based on direct digilal synthesis(DDS), researched the implementation of system, at last parts of testing result was given.
