| Abstract: | A multi-mode and multi-waveform radar signal generator based on DDS was designed with AD9854 and FPGA,which can be used to simulate various pulse signal waveforms such as LFM,NLFM,single frequency and phase code with wide Doppler modulation and long time delay adjustment.The performance of pulse compression and signal processing unit can be verified effectively.The testing result shows that the system can satisfy the requirement. |
