Application of Direct Digital Synthesis Circuit in Radar Signal Design [Copy link]

With the development of science and technology, radar has higher and higher requirements for signals. Radar signals must have the ability of frequency agility, waveform parameter agility and adaptive frequency hopping. Traditional analog methods can only generate a single radar signal, and direct digital synthesis ( DDS ) is the best way to solve this problem. The dedicated DDS circuit AD9854 can generate various signal forms such as dot frequency, linear frequency modulation, FSK , BPSK, etc., with good amplitude and phase consistency, and has the advantages of simple circuit control, convenience and flexibility, and high reliability.
