[Abstract]:In order to overcome the electronic bottleneck of the traditional electronic signal generator in operating bandwidth and working frequency, and to meet the needs of the future application of optical ultra-wideband (UWB) system, a photonic ultra-wideband (UWB) signal generation method is proposed. Based on the principle of microwave photon differentiation, this method can process Gao Si pulse flexibly in optical domain, and then realize the generation of UWB signal. Through theoretical derivation and computer simulation, the proposed method is analyzed and verified. The results show that the method can generate and modulate various UWB signal waveforms according to the need. In addition, by optimizing the configuration of the system, a frequency adjustable zero point can be introduced into the power spectrum of the output UWB signal, thus avoiding the interference between the UWB signal and the existing WiFi signal.
