Abstract

In order to overcome the defects of traditional analog method to generate nanosecond impulse pulse, this paper designs a new full-digital and full-coherent source which is suitable for the generation of nanosecond impulse pulse according to signal theory and DDS theory. In order to generate sinc impulse whose spectrum is rectangular, two parameters which influence its spectrum and bandwidth are analyzed. The test results show that this source can generate bipolar sinc impulse pulse whose pulse width is 2.72ns, bandwidth 500MHz and PRF 48ns with 2GHz sampling rate. The PRF stability is determined by the phase noise of sampling clock, and the waveform stability is determined by the gain error and offset error of the DAC.
