This paper puts forward a design of frequency synthesizer based on DDS for Kaband 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.
