A Ka-Band Radar Frequency Synthesizer Design Based on DDS Technology
Gao Weiliang, Baopeng Li · DEStech Transactions on Computer Science and Engineering · 2019
This paper puts forward a design of frequency synthesizer based on DDS for Ka-band radar signal simulation. RF signal is generated through the AD9854 DDS chip driving the PLL and VCO. The testing results showed that this Ka-band frequency synthesizer has low phase noise and wider bandwidth, and can generate Ka-band continuous wave signal, LFM signal for radar signal simulation.
