Wenfeng Dong, Quan Liu, Shirui Peng, Haihong Li · 2009
A radar waveform generator is designed, employing directly digital modulation method based on DDS and SOPC technology. It is able to output arbitrary signals with amplitude, frequency or phase modulation under the control of signal characteristics description words out putted from an external computer. Up to four waveforms with different modulation can be generated simultaneously by single circuit module with good quality. Parameters of each waveform are programmable and easy to be updated.
