Development of DDS Digital Synthetic Frequency for Chirp Signal Generation
Guo Zhen-yong · Modern Radar · 2005
The basic theory of direct digital syn th esis technology and the function of AD9854 are introduced, and a design of LFM c hirp signal generation using CPLD and AD9854 is put forward, then the principle of LFM chirp signal generation using CPLD and AD9854 is described in detail. At last, the experimental results of the design are given. The practical applicatio n achieves preferable effect.
