| Abstract: | In this paper, the design and implementation of a high performance ultra wideband LFM waveform generator at VHF/UHF band are introduced. The design ideas for a high performance ultra wideband LFM waveform generator are firstly described. Then, a generation scheme for ultra wideband LFM waveforms is presented according to the baseband digital generation method combining the bandwidth extension method via frequency doubling. An experimental system has been implemented and tested. The results show that the ultra wideband LFM waveform generator achieves very high performance. |
