Introduce the digital generation method of ultra wide band LFM baseband and its realization technology. First of all, two main digital generation methods of LFM signal are briefly described and compared. Then, a scheme of generating UWB chirp signal is proposed based on the waveform storage direct reading method. The main key technologies of baseband digital generation are analyzed and carried out System implementation and testing. The test results show that the proposed method is feasible.
